The PGC is an intelligent, accelerated 2D and 3D video card for the [[Driver:IBM PCs|early PCs]], marketed by IBM from 1984 to 1987. Screen resolution is 640x480, 256 colors (8-bit) from palette of 4096 (12-bit). The board has an optional CGA emulation mode which is not currently implemented in MAME as of 0.275.

Firmware running on the onboard CPU (an Intel 8088) exchanges commands and results with the host via a shared memory region; there is no direct framebuffer access. Bitmap support is rather simple -- a single write to frame buffer may change up to 20 adjacent pixels in one scan line. The primary purpose of the board is to draw 3D wireframe graphics (or 2D geometric shapes) and offload this from the main CPU. In other words, this is the first commercially sold personal computer GPU.

MAME supports it as slot device "pgc" for ISA bus in the ibm5150 (IBM PC) driver. As there is no CGA emulation, this needs to be used along side a CGA board, for example in slot 5 on a ibm5150, with the other boards left as default. The two 4:3 monitors will be displayed side by side, which works well on a 16:9 display. In theory this should work in the ibm5160 (IBM PC XT) and ibm5170 (IBM PC AT) and some other ISA bus PC compatibles. The real PGC is reported to have trouble with faster computers.

== Software ==
=== Advanced Diagnostics ===
The IBM PC Advanced Diagnostics 2.25 (and perhaps other versions) do support the PGC, however the MAME emulation is currently failing the test.

=== AutoCAD ===
The card was supported by CAD software (AutoCAD 2.6j is known to work).

=== CompuShow ===
CompuShow (CShow) image viewer and its successor 2show are reported to work.

Open source utilities written in C (https://www.seasip.info/VintagePC/pgcbmp.zip) that speak directly to the card and provide examples of how to use it. Also available on github, [https://github.com/trguhq/pgctalk PGCTALK] and [https://github.com/trguhq/pgcbmp PGCBMP].

[[File:PGC-BMP.png]]

=== VDI ===
PGC is supported by the IBM Personal Computer Graphics Development Toolkit via the VDI (virtual device interface) driver.

== Compatible boards ==
Several boards with varying degrees of compatibility were made by other manufacturers.

===Matrox PG series===
A number of cards based loosely on the IBM PGC were made by Matrox for PC-compatible computers and other platforms. Model numbers are PG-640, -641, -1280, -1281, PG2- (Micro-Channel), QG- (DEC MicroVAX Q-Bus), MG- (Multibus), VG- (VME). The PG-640 used National Semiconductor NS32016 microprocessor and later versions added the TI TMS34010 graphics accelerator (TIGA) as well as other support chips. The TIGA boards appear to deviate significantly from the PGC standard and may not be compatible at all.

===Other cards===
* Dell NEC MVA-1024 card
* Everex EV-660 EPGA
* Orchid Technology TurboPGA
* Vermont Microsystems IM-640, IM-1024
* Verticom H-16, -16B, -256, M-256E are believed to be in some way PGC compatible or derivative, with the model number indicating number of colors on screen. They use Motorola 68000 series processors and several custom ASICs.

Thisisamigaspeaking: /* Compatible boards */

= IBM Professional Graphics Controller =
The PGC is an intelligent, accelerated 2D and 3D video card for the [[Driver:IBM PCs|early PCs]], marketed by IBM from 1984 to 1987. Screen resolution is 640x480, 256 colors (8-bit) from palette of 4096 (12-bit). The board has an optional CGA emulation mode which is not currently implemented in MAME as of 0.275.

Firmware running on the onboard CPU (an Intel 8088) exchanges commands and results with the host via a shared memory region; there is no direct framebuffer access. Bitmap support is rather simple -- a single write to frame buffer may change up to 20 adjacent pixels in one scan line. The primary purpose of the board is to draw 3D wireframe graphics (or 2D geometric shapes) and offload this from the main CPU. In other words, this is the first commercially sold personal computer GPU.

MAME supports it as slot device "pgc" for ISA bus in the ibm5150 (IBM PC) driver. As there is no CGA emulation, this needs to be used along side a CGA board, for example in slot 5 on a ibm5150, with the other boards left as default. The two 4:3 monitors will be displayed side by side, which works well on a 16:9 display. In theory this should work in the ibm5160 (IBM PC XT) and ibm5170 (IBM PC AT) and some other ISA bus PC compatibles. The real PGC is reported to have trouble with faster computers.

== Software ==
=== Advanced Diagnostics ===
The IBM PC Advanced Diagnostics 2.25 (and perhaps other versions) do support the PGC, however the MAME emulation is currently failing the test.

=== AutoCAD ===
The card was supported by CAD software (AutoCAD 2.6j is known to work).

=== CompuShow ===
CompuShow image viewer claims support, but fails to display anything (apparently, it was tested on a 3rd-party compatible card, with extended command set).

=== Lawrence Berkeley National Laboratory demo ===
Public domain "IEA/ORAU Long-Term Global Energy-CO2 Model" software (DOI: 10.3334/CDIAC/ess.cmp002, https://web.archive.org/web/20230604083458/https://cdiac.ess-dive.lbl.gov/ftp/cmp002/), using the VDI driver for PGC to display its simulation results:

Open source utilities written in C (https://www.seasip.info/VintagePC/pgcbmp.zip) that speak directly to the card and provide examples of how to use it. Also available on github, [https://github.com/trguhq/pgctalk PGCTALK] and [https://github.com/trguhq/pgcbmp PGCBMP].

[[File:PGC-BMP.png]]

=== VDI ===
PGC is supported by the IBM Personal Computer Graphics Development Toolkit via the VDI (virtual device interface) driver.

== Compatible boards ==
Several boards with varying degrees of compatibility were made by other manufacturers.

===Matrox PG series===
A substantial number of cards based loosely on the IBM PGC were made by Matrox for PC-compatible computers and other platforms. Model numbers are PG-640, -641, -1280, -1281, PG2- (Micro-Channel), QG- (DEC MicroVAX Q-Bus), MG- (Multibus), VG- (VME). The PG-640 used National Semiconductor NS32016 microprocessor and later versions added the TI TMS34010 graphics accelerator as well as other support chips.

== 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.

=IBM PC and derivatives=

MAME has drivers for the IBM PC (ibm5150), PC XT (ibm5160), and PC AT (ibm5170), among other PC compatible systems.

After launching the driver and selecting a title from the software list you will be prompted to select from the available BIOS ROMs for this driver. The ROMs are loaded from your ROM paths, as is the normal (floppy) software, and the CHDs (hard disk) images. The Software List paths are not searched for these images.

If you have multiple graphics cards (assuming they can co-exist in a PC, like MDA and CGA, or CGA and PGC) they will all be displayed on your screen at once. A widescreen is useful for displaying two 4:3 outputs side by side.

== Menu ==
The keyboard by default is directed to the emulator so it will appear as native to the system. Scroll lock (by default) will enable MAME commands, such as escape to quit, F12 to screenshot, and tab to bring up the system menu.

=== DIP Switches ===
These are accurate to the emulated systems and may be needed to configure different graphics cards and such depending on what is installed.

=== File Manager ===
Here you can set which images are being used for the disks. The floppies are changed immediately.

=== Slot Devices ===
Here you pick which drivers are loaded for expansion cards. Some knowledge of IBM PCs will be required if changing the defaults. These changes will require the system to be restarted.

= IBM Professional Graphics Controller =
The PGC is an intelligent, accelerated 2D and 3D video card for the [[Driver:IBM PCs|early PCs]], marketed by IBM from 1984 to 1987. Screen resolution is 640x480, 256 colors (8-bit) from palette of 4096 (12-bit). The board has an optional CGA emulation mode which is not currently implemented in MAME as of 0.275.

Firmware running on the onboard CPU (an Intel 8088) exchanges commands and results with the host via a shared memory region; there is no direct framebuffer access. Bitmap support is rather simple -- a single write to frame buffer may change up to 20 adjacent pixels in one scan line. The primary purpose of the board is to draw 3D wireframe graphics (or 2D geometric shapes) and offload this from the main CPU. In other words, this is the first commercially sold personal computer GPU.

MAME supports it as slot device "pgc" for ISA bus in the ibm5150 (IBM PC) driver. As there is no CGA emulation, this needs to be used along side a CGA board, for example in slot 5 on a ibm5150, with the other boards left as default. The two 4:3 monitors will be displayed side by side, which works well on a 16:9 display. In theory this should work in the ibm5160 (IBM PC XT) and ibm5170 (IBM PC AT) and some other ISA bus PC compatibles. The real PGC is reported to have trouble with faster computers.

== Documentation ==
A summary of firmware capabilities is documented (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). The IBM Personal Computer Professional Graphics Controller Technical reference is fairly comprehensive (https://www.minuszerodegrees.net/oa/OA%20-%20IBM%20Professional%20Graphics%20Controller.pdf).

== Software ==
=== Advanced Diagnostics ===
The IBM PC Advanced Diagnostics 2.25 (and perhaps other versions) do support the PGC, however the MAME emulation is currently failing the test.

=== AutoCAD ===
The card was supported by CAD software (AutoCAD 2.6j is known to work).

Driver:Soviet PCs

2025-04-12T15:57:13Z

Thisisamigaspeaking:

= 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 [[Driver:IBM PCs|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

=== Screenshots ===
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

=== Screenshots ===
The Immortal Player - trainer for '80s PC games.

[[File:Poisk-1 Immortal Player.png]]

== 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 '@'.

The PGC is an intelligent, accelerated 2D and 3D video card for the [[Driver:IBM PCs|early PCs]], marketed by IBM from 1984 to 1987. Screen resolution is 640x480, 256 colors (8-bit) from palette of 4096 (12-bit). The board has an optional CGA emulation mode which is not currently implemented in MAME as of 0.275.

Firmware running on the onboard CPU (an Intel 8088) exchanges commands and results with the host via a shared memory region; there is no direct framebuffer access. Bitmap support is rather simple -- a single write to frame buffer may change up to 20 adjacent pixels in one scan line. The primary purpose of the board is to draw 3D wireframe graphics (or 2D geometric shapes) and offload this from the main CPU.

MAME supports it as slot device "pgc" for ISA bus in the ibm5150 (IBM PC) driver. As there is no CGA emulation, this needs to be used along side a CGA board, for example in slot 5 on a ibm5150, with the other boards left as default. The two 4:3 monitors will be displayed side by side, which works well on a 16:9 display. In theory this should work in the ibm5160 (IBM PC XT) and ibm5170 (IBM PC AT) and some other ISA bus PC compatibles. The real PGC is reported to have trouble with faster computers.

Thisisamigaspeaking:

= 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 [[Driver:IBM PCs|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

=== Screenshots ===
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

=== Screenshots ===

[[File:Poisk-1 Immortal Player.png]]

== 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 '@'.

Thisisamigaspeaking: basic information

=IBM PC and derivatives=

MAME has drivers for the IBM PC (ibm5150), PC XT (ibm5160), and PC AT (ibm5170), among other PC compatible systems.

After launching the driver and selecting a title from the software list you will be prompted to select from the available BIOS ROMs for this driver. The ROMs are loaded from your ROM paths, as is the normal (floppy) software, and the CHDs (hard disk) images. The Software List paths are not searched for these images.

== Menu ==
The keyboard by default is directed to the emulator so it will appear as native to the system. Scroll lock (by default) will enable MAME commands, such as escape to quit, F12 to screenshot, and tab to bring up the system menu.

=== DIP Switches ===
These are accurate to the emulated systems and may be needed to configure different graphics cards and such depending on what is installed.

=== File Manager ===
Here you can set which images are being used for the disks. The floppies are changed immediately.

=== Slot Devices ===
Here you pick which drivers are loaded for expansion cards. Some knowledge of IBM PCs will be required if changing the defaults. These changes will require the system to be restarted.

CompuShow image viewer claims support, but fails to display anything (apparently, it was tested on a 3rd-party compatible card, with extended command set).

=== Lawrence Berkely National Laboratory demo ===
Public domain "IEA/ORAU Long-Term Global Energy-CO2 Model" software (DOI: 10.3334/CDIAC/ess.cmp002, https://cdiac.ess-dive.lbl.gov/ftp/cmp002/), using VDI driver for PGC to display its simulation results:

=== PGCBMP and PGCTALK ===
Open source utilities written in C (https://www.seasip.info/VintagePC/pgcbmp.zip) that speak directly to the card and provide examples of how to use it.
