Driver:Mac 68K

Apple Macintosh series (Motorola 680x0-based)

Designed by a team led by Steve Jobs, the Macintosh was Apple's follow-up to the Apple II series that finally stuck, after many attempts. Macintosh computers are still being made today, albeit with very different hardware and software technology.

Quickstart

For most of these machines, it is strongly recommended that you get a pre-installed hard drive image to boot from (look for the "Software List CHDs" collection from your favorite ROM provider). Only the very early models were primarily floppy oriented.

Models and Clones

• Macintosh 128K (1984 - driver name mac128k)

- The original machine. Includes a 68000 CPU, 128K of RAM, an integrated 9" black and white CRT monitor with a resolution of 512x384 pixels, a 3.5" single-sided 400K floppy drive, two serial ports, a keyboard, and a mouse.

• Macintosh 512K (1984 - driver name mac512k)

- The so-called "Fat Mac". Identical to the 128K, but with 512K of RAM as the name suggests.

• Macintosh Plus (1986 - driver name macplus)

- The first significant update to the Mac. Comes with 1MB of RAM and SIMM slots to expand up to 4MB, replaces the single-sided floppy drive with a double-sided 800K unit, and adds a SCSI port for hard disks and CD-ROMs. Everything else is the same.

• Macintosh 512KE (1984 - driver name mac512ke)

- A Macintosh 512K, but with the newer ROMs from the Macintosh Plus and an 800K double-sided floppy disk drive .

• Macintosh SE (1987 - driver name macse)

- A further evolution of the Macintosh Plus, with a cost-reduced motherboard, a processor-direct slot for a single expansion card, and introducing the Apple Desktop Bus (ADB) that debuted on the Apple IIgs to connect the keyboard and mouse.

• Macintosh SE FDHD (1987 - driver name macsefd)

- Same as the Macintosh SE, but replacing the floppy controller chip with the new SWIM (Sander/Wozniak Integrated Machine) chip and the 800K double-sided floppy drive with a 1.44MB "SuperDrive", which can also read and write the older 400K and 800K disks, as well as MS DOS-format 720K and 1.44MB disks.

• Macintosh Classic (1990 - driver name macclasc)

- Same as the Macintosh SE FDHD, but cost-reduced even further, primarily by removing the processor-direct slot once again.

• Macintosh II (1987 - driver name macii)

- The first major redesign of the Macintosh. Includes a 15 MHz 68020 processor, SIMMs to expand up to 128MB of RAM, 6 NuBus slots, a built-in 800K double-sided floppy drive, and a built-in SCSI hard disk. Capable of color and of having multiple video cards and monitors connected.

• Macintosh II FDHD (1988 - driver name mac2fdhd)

- A Macintosh II with the same upgrades as the Macintosh SE FDHD - the new SWIM floppy controller and 1.44MB "SuperDrive".

• Macintosh IIx (1988 - driver name maciix')

- A Macintosh II FDHD with the processor replaced by a 15 MHz 68030. The 68030 is faster than the 68020 at the same clock and includes on-board memory management and floating-point acceleration.

• Macintosh IIcx (1989 - driver name maciicx')

- A Macintosh IIx in a more compact case with fewer NuBus slots.

• Macintosh SE/30 (1989 - driver name macse30')

- A Macintosh IIx in the same case as the original Macs with the same 9" 512x384 CRT monitor. Has no NuBus slots but does have a single processor-direct slot for expansion.

• Macintosh IIci (1989 - driver name maciici')

- A Macintosh IIcx in a more rounded case with on-board color video and a slightly faster processor.

• Macintosh IIsi (1990 - driver name maciisi')

- A Macintosh IIci with a cost-reduced motherboard, using the new "Egret" microcontroller for ADB and PRAM.

Configuring slots

To find out what a version of MAME supports for configurable slot and port devices, run MAME with the -listslots parameter on the commandline. Some Macs have no slots, some have up to 6. NuBus slots use the command line convention nbX, where X is the slot's name, usually 9, a, b, c, d, or e.

To empty a slot which has a card in it by default, use the -sl switch for the slot followed by two double quotes. For instance, to remove the default video card in slot 9 on a Mac II, you'd type -nb9 "".

NuBus slots generally support all of these cards:

More configuration

The -ramsize switch controls the amount of RAM on most Macs.

To see what kinds of disk and other images are accepted for a given configuration, use the -listmedia option alongside whatever slot cards you want to use. Most Macs have at least one -hard / -harddisk option, and a -flop1 for a floppy drive.

Note that some cards add configurable slots or ports of their own. You can see those by adding the card and appending -listslots to the end of the command line.

A note about hard drive and CD-ROM images

MAME versions before 0.214 were only able to use images that had been converted to MAME's own CHD format. This is no longer the case.
