Driver:Soviet PCs

Shattered: /* Soviet PC clones */

= Soviet PC clones =

== ES 1840 and ES 1841 ==
These were intended for professional users -- monitor, printer, hard disk drive (in model 1841), development kit and productivity software were included.

Models 1840 and 1841 mimic IBM PC 5150 and IBM PC XT 5160, but are not 100% compatible -- some features are missing (no support for 8087 math co-processor in the 1840), some hardware is completely (serial port) or partially (keyboard scan codes) incompatible. The bus is ISA, cards use a different form factor (20x24 cm with a single 135-pin connector). Video adapters are extended versions of MDA and CGA (both support downloadable text-mode fonts). Model 1841 could route sound from optional speech synthesis board to internal speaker and supported a bus mouse.

1840 and 1841 shipped with customized versions (likely not authorized by original developers) of operating systems and application software -- CP/M-86, MS-DOS 3, SuperCalc, WordStar etc. CP/M and DOS were fully translated to Russian, down to command names. The hardware and BIOS is compatible enough that unmodified software will also run.

MAME emulates all standard hardware in both models, except serial ports. Driver names are ec1840 and ec1841. Some of the software is in the softlist.

On startup, keyboard input is in Cyrillic mode; F11 switches to Latin, F12 -- back to Cyrillic. Help key (used by CP/M) is mapped to Pause/Break.

Model 1841 includes a demo disk ('demo' in the softlist), probably intended for use on trade shows. A full recording is on YouTube -- https://www.youtube.com/watch?v=1pj-CVIMgn4

ES1840 running Alpha-DOS -- all messages and commands are in Russian:

[[File:ES1840 Alpha-DOS.png]]

== ES 1842 ==
An modifed clone of IBM PC AT 5170 (no 16-bit DMA etc.). Has used a modified copy of Intel 8086 CPU (adds PUSHA instruction and invalid opcode interrupt) and additional hardware to support emulation of Intel 80286 features.

MAME driver name is ec1842 (NOT_WORKING).

== Poisk-1 ==
A cheap MS-DOS compatible clone with built-in keyboard and four expansion slots. Designed in 1988, revised in 1989 and 1991. Was rather popular, judging by the range of available expansion cards (first- and third-party). CPU is 8088 clone clocked at 5 MHz.

Since the hardware is so different from the original PC (DMA controller is missing, video hardware is somewhat CGA-compatible but has no mc6845 or native text mode, and so on), some software (mostly games) was patched to run on the Poisk.

MS-DOS will run on the machine (unmodified or one of its many clones, including "MDOS Poisk"); and there's an unique "One-Track System" (available in the softlist). Floppy BIOS assumes a 80-track (720KB) drive is connected; 360KB floppies must have media descriptor byte 0xFC or higher.

MAME emulates revision 1991 of this machine, with three add-on cards (ROM cartridge, floppy interface, and sound card). Driver name is poisk1. Keyboard layout toggle is mapped to Right Control key.

Sound card supports digitized sound I/O at 10 kHz sampling rate, MIDI in/out, and 6 channels of square wave output (driven by two 8253 timers); only DAC is currently supported by MAME. A recording of speech synthesis demo supplied with the card is on YouTube -- https://www.youtube.com/watch?v=y4OGNWjyqbI

== Poisk-2 ==
A more compatible XT clone, has onboard RTC chip (clone of mc146818) and EMS support.

MAME driver name is poisk2 (NOT_WORKING).

== Elektronika MS 1502 ==
Another MS-DOS compatible clone with built-in keyboard. Two expansion slots. A bit more compatible and faster than Poisk-1 (CGA is fully implemented in an ASIC; CPU clock is 5.33 MHz) and has more onboard hardware (serial and parallel ports), but still no DMA or Intel floppy chip.

Like Poisk-1, will run original MS-DOS, and has its own unique MS-DOS clone (Sigma Four DOS). Will also run One-Track System; both are in softlist.

MAME emulates all standard hardware of MS 1502, plus two add-on cards (ROM cartridge with BASIC, and floppy interface). Driver name is mc1502. Keyboard layout toggle is mapped to Right Alt key. To enter BIOS monior, press Enter twice after memory test completes. To boot from first floppy, enter '@'.

Driver:Soviet terminals

2019-12-31T14:39:48Z

Shattered: /* Elektronika SM 7238 / Электроника СМ 7238 (1989) */

All of these terminals emulate one or more of DEC terminals (VT52, VT100, or VT200 series), and all support some variant of [https://en.wikipedia.org/wiki/KOI_character_encodings KOI character set] in addition to modified ASCII (dollar sign is replaced by generic currency sign, U+00A4). Keyboard layout is usually [https://en.wikipedia.org/wiki/JCUKEN Latin JCUKEN].

== 15IE-00-013 / 15ИЭ-00-013 (circa 1980) ==
DEC VT52 compatible (minus Hold Screen mode, printer support and graphics character set), has native command set as well. Green phosphor CRT. Keyboard is capacitive; has number pad, an editing keypad, and a row of function keys. Terminal is configurable via soft-switches in setup mode. There is no NVRAM. Host connection is RS232 or current loop, from 75 up to 9600 bps at 8 bit, no parity, no hardware flow control.

MAME driver name is '''ie15''' -- can be used standalone, or attached to any other emulation via serial port. However, it is not very user-friendly -- defaults to upper-case, shift key acts as a toggle (i.e. locking shift), and default emulation mode is native, which has no hardware tabs. To make it less annoying, switch key click off and emulation to VT52:

=== Setup mode ===
To enter setup, press PrtScr. Cursor should appear in status line at the top. Use arrow keys to navigate and keypad '*' to change values, and PrtScr to exit setup.

* Serial port speed. Leave at 9600.

Group II
* Cursor shift (meaning unknown)
* Keyboard autorepeat -- 0: off, 1: on (does not work in MAME)

= HP Integral PC =
The Integral PC (model 9807A) was a portable Unix workstation released by Hewlett-Packard in 1985. Operating system ran from ROM; software would be run from built-in 3.5" floppy drive, or from an external hard disk attached to HP-IB bus.

The OS is HP-UX, originally version 1.0 based on AT&T System III, later upgraded to 5.0 based on System V. Neither had TCP/IP networking support, but serial interfaces were available (supported by Kermit and UUCP software).

More info at Wikipedia -- https://en.wikipedia.org/wiki/HP_Integral_PC and HP Journal -- http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1985-10.pdf

MAME emulates essential parts of the IPC:
* keyboard and mouse
* graphics processor and monochrome display (512x255 in the standard model, 640x400 in unreleased prototype)
* internal floppy drive
* memory expansion (up to 7 MB)
* HP-IB (IEEE488) controller

Not emulated: built-in printer, sound generator, any of the expansion cards.

Software is available from HP Museum and other sites, and is documented in MAME softlist.

Shattered:

== Stage 1: ct486 PC driver setup for all OSes ==

Handy things to have include:
* [http://rbelmont.mameworld.info/mess_pchd.zip Preformatted blank 2GB and 4GB hard disk images.]
* [http://rbelmont.mameworld.info/pcboot.zip A DOS 7.1 boot disk with third party CD-ROM drivers.]

Step 1: Extract the hard disk images. Make a copy of one of them named after the OS you're going to install, such as win2k.chd. (For Win 95/98/ME you must use the 2GB disk only as a source!)

Step 2: Start the ct486 driver with the following minimal options: -ramsize 64M -hard1 win2k.chd (or whatever you named it).

[[File:Ct486-setup1.png|Setup example image]]

If you are starting from clear NVRAM, you'll see this message. Press F1 to enter SETUP. If you have previously used the driver, press DEL to enter SETUP during the RAM count-up.

* Choose the first option "STANDARD CMOS SETUP" and press Enter twice, skipping the dire warning.

[[File:Ct486-setup2.png|Setup example image]]

* Setup the date and time to current and move the cursor down to the Hard Disk C: Type.
* Press Page Up to get type 47 USER TYPE.
* Use the right arrow and number keys to change Cyln to 4161 (2GB) or 8322 (4GB), Head to 16 and Sect to 63. Do not change WPcom or Lzone.
* Select Floppy Drive A and press PAGE UP/PAGE DOWN until it's set to "1.44 MB 3 1/2".
* Press Esc and choose ADVANCED CMOS SETUP. Press Enter to skip the warning screen once again and scroll down to System Boot Up Sequence.

[[File:Ct486-setup3.png|Setup example image]]

* Press PAGE UP/PAGE DOWN to select "A: C:" as shown
* Press Esc.

Driver:Soviet PDP-11s

2019-08-12T13:16:19Z

Shattered:

Soviet Union built many systems with Digital Equipment Corporation's PDP-11 ISA -- some were straight-up clones of PDP-11 models, down to the chipset, others reimplemented the architecture -- see http://www.dbit.com/pub/pdp11/faq/faq.pages/Soviet11s.html for background information. They were used much like the originals -- for timesharing, industrial process control, data acquisition and so on, including personal computing and embedded use.

Out of all PDP-11 processor variants, MAME currently emulates only T-11 single-chip CPU, intended for embedded applications. DEC VT240 terminal (and its clone, [[Driver:Soviet terminals|Elektronika MS 7105]]) uses it, along with another Elektronika system, MS 0515 -- an unusual choice for a desktop. MAME emulates both of them. Other professional PCs (DVK series), educational machine (UK-NC aka Elektronika MS 0511) and home computers (BK-001x series) used K1801 chipset, which is not emulated.

However, it is possible to use MAME as a terminal emulator connected to a simulated PDP-11 running in SIMH. As an example of this, the [[MAME_and_SIMH|linked guide]] shows how to install RT-11 operating system in a simulated PDP 11/23.

== Elektronika MS 0515 ==
A rather obscure machine, possibly intended as educational or gaming system -- video memory layout is clearly inspired by ZX Spectrum, and a few ports of Spectrum games exist. Was designed and built by the "Processor" firm in Voronezh (same place that produced many other PDP-11 clones).

MAME driver name is ms0515. Hardware emulation is not 100% complete, but enough to boot the operating systems (OSA and Omega, a/k/a modified DEC RT-11) and run the games:

History Simulator (SIMH) recreates a range of historically important computing systems, including DEC PDP-11. System console terminal for a PDP-11 system would usually be one of DEC's video- or printing terminals (DEC VT100 or LA36 "DECwriter II", for example). SIMH lets its user work with simulated system from a real terminal (attached to physical serial port), or via a terminal emulator of their choice, such as MAME.

You will need:

* SIMH 3.9 or newer -- prebuilt Windows binaries: https://github.com/simh/simh/releases/download/v3.9-0/simhv39-0-exe.zip or https://github.com/simh/Win32-Development-Binaries
* MAME 0.177 or newer
* Distribution media for RT-11 5.3 operating system -- via http://gunkies.org/wiki/Installing_RT-11_5.3_on_SIMH
* Optional: user manuals
** operating system -- http://www.bitsavers.org/pdf/dec/pdp11/rt11/v5.1_Jul84/
** terminal -- http://www.bitsavers.org/pdf/dec/terminal/vt240/EK-VT240-UG-003_VT240_Series_Owners_Manual_Dec84.pdf

=== Step 1: Configure DEC VT240 terminal emulator ===

* start MAME ('mame vt240') and wait for self-test to complete ("VT240 OK" screen)
* press F3 to enter setup menu. Use cursor keys and keypad Enter key to navigate and change options.
* reset terminal to factory default settings -- choose "Default" in "Set-Up Directory" menu.
* set serial port speed to 9600 -- enter "Comm" menu and change from "Transmit=4800" to "Transmit=9600", then exit this menu "To Directory"
* save settings to terminal NVRAM ("Save") and exit MAME.

[[File:VT240 OK Transmit 9600.png]]

=== Step 2: Configure PDP-11 simulation ===
* follow the gunkies.org guide, but alter inst.ini -- replace "boot rl1" with "set console telnet=1123" in inst.ini. This will configure a remote console on TCP port 1123, and disable automatic boot of simulated system.

=== Step 3: Install RT-11 ===
* start SIMH -- expected output is:
Listening on port 1123
sim>
* start MAME with null modem cable 'attached' to SIMH and wait for it to boot to "VT240 OK" screen:
mame vt240 -bitb socket.localhost:1123
* start simulation in SIMH -- from sim> console enter:
boot rl1
* follow the installer's prompts.

However, it is possible to use MAME as a terminal emulator connected to a simulated PDP-11 running in SIMH. As an example of this, the [[MAME_and_SIMH|linked guide]] will show how to install RT-11 operating system in a simulated PDP 11/23.

== Elektronika MS 0515 ==
A rather obscure machine, possibly intended as educational or gaming system -- video memory layout is clearly inspired by ZX Spectrum, and a few ports of Spectrum games exist. Was designed and built by the "Processor" firm in Voronezh (same place that produced many other PDP-11 clones).

MAME driver name is ms0515. Hardware emulation is not 100% complete, but enough to boot the operating systems (OSA and Omega, a/k/a DEC RT-11) and run the games:

Driver:Agat

2019-07-11T19:59:42Z

Shattered: /* Screenshots */

Agat series are almost, but not quite, entirely unlike Apple II clones. CPU is the same (real 6502 chips; early prototype used bitsliced clone), bus architecture, some of the onboard devices, and floppy format likewise; the rest is different -- video modes, ROM entry points, expansion cards, and so on. NTSC color artifacting is not used -- video output is either RGB or grayscale. Unlike Apple, the machines were not targeted at home users -- the intent was to deliver an educational aid for a high school 'CS' course.

== Models ==
* Agat-7 (1985), driver name '''agat7'''

7 expansion slots, 5 usable -- slot 1 is always taken by CPU card, slot 0 reserved for "Apple video" card or SECAM encoder. 32K of RAM on the motherboard, cassette and game controller I/O, a 1-bit speaker clicker. 5 video modes (32x32 color and 64x32 mono text; 64x64 and 128x128 color, 256x256 mono graphics).

* Agat-9 (1988), driver name '''agat9''' (WIP)

CPU moved to motherboard, slot 0 removed, onboard memory expanded to 128K. New 840K floppy controller (incompatible with Disk II), new native video modes (128x128 and 256x256 color, 512x256 mono graphics). Apple compatibility mode (requires Apple ROM image to be loaded from disk) -- equivalent to 48K II with 16K language card.

== Using Agat-7 in MAME ==
MAME emulates motherboard revision with 32K of onboard memory. Revisions that could support 64K and 128K existed as well, but it's unclear how many of those were shipped and which software supported them.

Default slot device configuration works with most software out of the box:
* slot 2: 32K language card
* slot 3: Disk II compatible floppy controller with two drives
* slot 4: serial/parallel card (configured for printing in Agat-Author text editor)
* slot 6: 32K RAM card

Native software is available from http://agatcomp.ru and http://agat-legacy.narod.ru/onebyone.htm; software for the Apple II will not run.

The driver is incomplete -- only bubble memory is supported (no external floppy or hard disks). Also, all known CCOS floppy disks were built for model 1101 and do not run on model 1129 (no other ROM is available yet). The driver applies ROM patches to work around both issues, allowing CCOS 3.0.1 to boot and run some software -- see notes at the start of driver file.

= IBM Professional Graphics Controller =
The PGC is an intelligent, accelerated 2D video card for the early PCs, marketed by IBM from 1984 to 1987. Screen resolution is 640x480, 256 colors from palette of 4096.

Firmware running on the onboard CPU (an Intel 8088) exchanges commands and results with the host via shared memory region; there is no direct framebuffer access. Acceleration is rather simple -- a single write to frame buffer may change up to 20 adjacent pixels in one scan line.

The card was supported by CAD software (AutoCAD 2.6j is known to work). CompuShow image viewer claims support, but fails to display anything (apparently, it was tested on a 3rd-party compatible card, with extended command set). Also supported by IBM Personal Computer Graphics Development Toolkit via VDI (virtual device interface) driver. A summary of firmware capabilities is documented on http://www.seasip.info/VintagePC/pgc.html and technical details are in the IBM Systems Journal article http://wayback.archive.org/web/20061015235146/http://www.research.ibm.com/journal/sj/241/ibmsj2401D.pdf.

MAME supports it as slot device "pgc" for ISA bus in ibm5160 (IBM PC XT) driver.

Driver:Soviet PDP-11s

Shattered:

Soviet Union built many systems with Digital Equipment Corporation's PDP-11 ISA -- some were straight-up clones of PDP-11 models, down to the chipset, others reimplemented the architecture -- see http://www.dbit.com/pub/pdp11/faq/faq.pages/Soviet11s.html for background information. They were used much like the originals -- for timesharing, industrial process control, data acquisition and so on, including personal computing and embedded use.

Out of all PDP-11 processor variants, MAME currently emulates only T-11 single-chip CPU, intended for embedded applications. DEC VT240 terminal (and its clone, [[Driver:Soviet terminals|Elektronika MS 7105]]) uses it, along with another Elektronika system, MS 0515 -- an unusual choice for a desktop. MAME emulates both of them. Other professional PCs (DVK series), educational machine (UK-NC aka Elektronika MS 0511) and home computers (BK-001x series) used K1801 chipset, which is not emulated.

However, it is possible to use MAME as a terminal emulator connected to a simulated PDP-11 running in SIMH. As an example of this, the linked guide will show how to install RT-11 operating system in a simulated PDP 11/03, and then run a few text-only games.

== Elektronika MS 0515 ==
A rather obscure machine, possibly intended as educational or gaming system -- video memory layout is clearly inspired by ZX Spectrum, and a few ports of Spectrum games exist. Was designed and built by the "Processor" firm in Voronezh (same place that produced many other PDP-11 clones).

MAME driver name is ms0515. Hardware emulation is not 100% complete, but enough to boot the operating systems (OSA and Omega, a/k/a DEC RT-11) and run the games:

Agat series are almost, but not quite, entirely unlike Apple II clones. CPU is the same (real 6502 chips; early prototype used bitsliced clone), bus architecture, some of the onboard devices, and floppy format likewise; the rest is different -- video modes, ROM entry points, expansion cards, and so on. NTSC color artifacting is not used -- video output is either RGB or grayscale. Unlike Apple, the machines were not targeted at home users -- the intent was to deliver an educational aid for a high school 'CS' course.

== Models ==
* Agat-7 (1985), driver name '''agat7'''

7 expansion slots, 5 usable -- slot 1 is always taken by CPU card, slot 0 reserved for "Apple video" card or SECAM encoder. 32K of RAM on the motherboard, cassette and game controller I/O, a 1-bit speaker clicker. 5 video modes (32x32 color and 64x32 mono text; 64x64 and 128x128 color, 256x256 mono graphics).

* Agat-9 (1988), driver name '''agat9''' (WIP)

CPU moved to motherboard, slot 0 removed, onboard memory expanded to 128K. New 840K floppy controller (incompatible with Disk II), new native video modes (128x128 and 256x256 color, 512x256 mono graphics). Apple compatibility mode (requires Apple ROM image to be loaded from disk) -- equivalent to 48K II with 16K language card.

== Using Agat-7 in MAME ==
Driver supports only 32K onboard memory. Motherboard could support 64K and 128K as well, but it's unclear how many of those were shipped and which software supported them.

Default slot device configuration works with most software out of the box:
* slot 2: 32K language card
* slot 3: Disk II compatible floppy controller with two drives
* slot 4: serial/parallel card (configured for printing in Agat-Author text editor)
* slot 6: 32K RAM card

Native software is available from http://agatcomp.ru and http://agat-legacy.narod.ru/onebyone.htm; software for the Apple II will not run.

= Soviet PC clones =

== ES 1840 and ES 1841 ==
These were intended for professional users -- monitor, printer, hard disk drive (in model 1841), development kit and productivity software were included.

Models 1840 and 1841 mimic IBM PC 5150 and IBM PC XT 5160, but are not 100% compatible -- some features are missing (no support for 8087 math co-processor in the 1840), some hardware is completely (serial port) or partially (keyboard scan codes) incompatible. The bus is ISA, cards use a different form factor (20x24 cm with a single 135-pin connector). Video adapters are extended versions of MDA and CGA (both support downloadable text-mode fonts). Model 1841 could route sound from optional speech synthesis board to internal speaker and supported a bus mouse.

1840 and 1841 shipped with customized versions (likely not authorized by original developers) of operating systems and application software -- CP/M-86, MS-DOS 3, SuperCalc, WordStar etc. CP/M and DOS were fully translated to Russian, down to command names. The hardware and BIOS is compatible enough that unmodified software will also run.

MAME emulates all standard hardware in both models, except serial ports. Driver names are ec1840 and ec1841. Some of the software is in the softlist.

On startup, keyboard input is in Cyrillic mode; F11 switches to Latin, F12 -- back to Cyrillic. Help key (used by CP/M) is mapped to Pause/Break.

Model 1841 includes a demo disk ('demo' in the softlist), probably intended for use on trade shows. A full recording is on YouTube -- https://www.youtube.com/watch?v=1pj-CVIMgn4

== ES 1842 ==
A clone of IBM PC AT 5170. Has used a modified copy of Intel 8086 CPU (adds PUSHA instruction and invalid opcode interrupt) and additional hardware to support emulation of Intel 80286 features.

MAME driver name is ec1842 (NOT_WORKING).

== Poisk-1 ==
A cheap MS-DOS compatible clone with built-in keyboard and four expansion slots. Designed in 1988, revised in 1989 and 1991. Was rather popular, judging by the range of available expansion cards (first- and third-party). CPU is 8088 clone clocked at 5 MHz.

Since the hardware is so different from the original PC (DMA controller is missing, video hardware is somewhat CGA-compatible but has no mc6845 or native text mode, and so on), some software (mostly games) was patched to run on the Poisk.

MS-DOS will run on the machine (unmodified or one of its many clones, including "MDOS Poisk"); and there's an unique "One-Track System" (available in the softlist). Floppy BIOS assumes a 80-track (720KB) drive is connected; 360KB floppies must have media descriptor byte 0xFC or higher.

MAME emulates revision 1991 of this machine, with three add-on cards (ROM cartridge, floppy interface, and sound card). Driver name is poisk1. Keyboard layout toggle is mapped to Right Control key.

Sound card supports digitized sound I/O at 10 kHz sampling rate, MIDI in/out, and 6 channels of square wave output (driven by two 8253 timers); only DAC is currently supported by MAME. A recording of speech synthesis demo supplied with the card is on YouTube -- https://www.youtube.com/watch?v=y4OGNWjyqbI

Like Poisk-1, will run original MS-DOS, and has its own unique MS-DOS clone (Sigma Four DOS). Will also run One-Track System; both are in softlist.

MAME emulates all standard hardware of MS 1502, plus two add-on cards (ROM cartridge with BASIC, and floppy interface). Driver name is mc1502. Keyboard layout toggle is mapped to Right Alt key. To enter BIOS monior, press Enter twice after memory test completes. To boot from first floppy, enter '@'.

All of these terminals emulate one or more of DEC terminals (VT52, VT100, or VT200 series), and all support some variant of KOI character set in addition to modified ASCII (dollar sign is replaced by generic currency sign, U+00A4). Keyboard layout is usually [https://en.wikipedia.org/wiki/JCUKEN Latin JCUKEN].

== 15IE-00-013 / 15ИЭ-00-013 (circa 1980) ==
DEC VT52 compatible (minus Hold Screen mode, printer support and graphics character set), has native command set as well. Green phosphor CRT. Keyboard is capacitive; has number pad, an editing keypad, and a row of function keys. Terminal is configurable via soft-switches in setup mode. There is no NVRAM. Host connection is RS232 or current loop, from 75 up to 9600 bps at 8 bit, no parity, no hardware flow control.

MAME driver name is '''ie15''' -- can be used standalone, or attached to any other emulation via serial port. However, it is not very user-friendly -- defaults to upper-case, shift key acts as a toggle (i.e. locking shift), and default emulation mode is native, which has no hardware tabs. To make it less annoying, switch key click off and emulation to VT52:

=== Setup mode ===
To enter setup, press PrtScr. Cursor should appear in status line at the top. Use arrow keys to navigate and keypad '*' to change values, and PrtScr to exit setup.

Group II
* Cursor shift (meaning unknown)
* Keyboard autorepeat -- 0: off, 1: on (does not work in MAME)

Group III
* Margin bell (at position 72) -- 0: off, 1: on
* Key click -- 0: on, 1: off
* Emulation mode -- 0: native, 1: VT52
* XON/XOFF flow control (unverified)

Group IV

* Parity check -- 0: off, 1: on
* Auto CR/LF on output -- 0: off, 1: on
* Status line -- 0: displayed, 1: not displayed

Group VI
* Hours, minutes and seconds since power on.

All of these terminals emulate one or more of DEC terminals (VT52, VT100, or VT200 series), and all support some variant of KOI character set in addition to modified ASCII (dollar sign is replaced by generic currency sign, U+00A4). Keyboard layout is usually [https://en.wikipedia.org/wiki/JCUKEN Latin JCUKEN].

== 15IE-00-013 / 15ИЭ-00-013 (circa 1980) ==
DEC VT52 compatible (minus Hold Screen mode, printer support and graphics character set), has native command set as well. Green phosphor CRT. Keyboard is capacitive; has number pad, an editing keypad, and a row of function keys. Terminal is configurable via soft-switches in setup mode. There is no NVRAM. Host connection is RS232 or current loop, from 75 up to 9600 bps at 8 bit, no parity, no hardware flow control.

MAME driver name is '''ie15''' -- can be used standalone, or attached to any other emulation via serial port. However, it is not very user-friendly -- defaults to upper-case, shift key acts as a toggle (i.e. locking shift), and default emulation mode is native, which has no hardware tabs. To make it less annoying, switch key click off and emulation to VT52:

=== Setup mode ===
To enter setup, press PrtScr. Cursor should appear in status line at the top. Use arrow keys to navigate and keypad '*' to change values, and PrtScr to exit setup.

Group I
* Serial port speed. Leave at 9600.

Group II
* Cursor shift (meaning unknown)
* Keyboard autorepeat -- 0: off, 1: on (does not work in MAME)
* n/a
* Cursor type (meaning unknown)

Group III
* Margin bell (at position 72) -- 0: off, 1: on
* Key click -- 0: on, 1: off
* Emulation mode -- 0: native, 1: VT52
* XON/XOFF flow control (unverified)

Group IV
* n/a
* (VT52 mode only) autowrap -- 0: on, 1: off
* (VT52 mode only) auto CR/LF on keyboard input -- 0: off, 1: on
* n/a

Group V
* Parity -- 0: even, 1: odd
* Parity check -- 0: off, 1: on
* Auto CR/LF on output -- 0: off, 1: on
* Status line -- 0: displayed, 1: not displayed

Group VI
* Hours, minutes and seconds since power on.

=== Screenshots ===
Modified Star Trek game (runs on a PDP-11 simulated by SIMH, simulator console is connected over network to 15IE emulation running in MAME).

== Elektronika MS 6102 / Электроника МС 6102 (1984) ==
DEC VT100-compatible terminal.

Keyboard protocol and host interface are the same as in DEC original; the rest of hardware is different (a pair of i8275's in place of custom DEC video chips, etc.) Keyboard (part number MS 7002) uses Hall effect sensors; a review is on Youtube: https://www.youtube.com/watch?v=EYr3j21aKvg

MAME driver name is '''ms6102''', emulation is not working yet.

== Elektronika SM 7238 / Электроника СМ 7238 (1989) ==
DEC VT220 compatible, also copies its menu layout. Some models support Tektronix 4010 and ReGIS graphics. Uses membrane keyboard (model KM-035).

MAME driver name is '''sm7238''', emulation is missing non-essential features (downloadable fonts, color).

== Elektronika MS 7105 / Электроника МС 7105 (circa 1991) ==
A 100% clone of DEC VT240, extended to support Cyrillic input and output, menus translated to Russian. Uses capacitive keyboard (part number MS 7004), protocol-compatible with DEC LK201.

MAME driver name is '''mc7105''', emulation is not 100% accurate (keyboard fails POST, some keys are not mapped). Unlike original, setup key is F4, not F3.

Driver:Soviet PDP-11s

Shattered:

Soviet Union built many systems with Digital Equipment Corporation's PDP-11 ISA -- some were straight-up clones of PDP-11 models, down to the chipset, others reimplemented the architecture -- see http://www.dbit.com/pub/pdp11/faq/faq.pages/Soviet11s.html for background information. They were used much like the originals -- for timesharing, industrial process control, data acquisition and so on, including personal computing and embedded use.

Out of all PDP-11 processor variants, MAME currently emulates only T-11 single-chip CPU, intended for embedded applications. DEC VT240 terminal (and its clone, Elektronika MS 7105) uses it, along with another Elektronika system, MS 0515 -- an unusual choice for a desktop. MAME emulates both of them. Other professional PCs (DVK series), educational machine (UK-NC aka Elektronika MS 0511) and home computers (BK-001x series) used K1801 chipset, which is not emulated.

However, it is possible to use MAME as a terminal emulator connected to a simulated PDP-11 running in SIMH. As an example of this, the linked guide will show how to install RT-11 operating system in a simulated PDP 11/03, and then run a few text-only games.

== Elektronika MS 0515 ==
A rather obscure machine, possibly intended as educational or gaming system -- video memory layout is clearly inspired by ZX Spectrum, and a few ports of Spectrum games exist. Was designed and built by the "Processor" firm in Voronezh (same place that produced many other PDP-11 clones).

MAME driver name is ms0515. Hardware emulation is not 100% complete, but enough to boot the operating systems (OSA and Omega, a/k/a DEC RT-11) and run the games:
