FM Towns Marty - Technical Specifications

Technical Specifications

CPU: 32-bit AMD 386SX processor

CPU Speed: 16 MHz

Graphics:

• Resolution: 352x232 up to 640x480
• 32768 color palette - 256 onscreen

The Marty had only composite and S-video output, no other video connectors are possible. As some FM Towns games were VGA-only, the Marty had a 15 kHz down-scan capability for displaying on a household TV screen.

Sprites:

Up to 1024 sprites,16 x 16 sprite size

Sound:

• 6 channel FM
• 8 channel PCM

RAM:

• 2 MB

Data Storage:

• CD-ROM, Single-speed (1x)
• Internal 3.5" HD floppy drive

Floppy disks must be formatted 1.2M (PC98-style). This can be done from the BIOS GUI. The Marty's disk drive does not support standard 1.44M or 720k FAT formatted 3.5" floppy disks. For a PC to be compatible with FM Towns Marty floppies it must have a disk drive, BIOS and OS that supports "3 Mode". There are also USB floppy drives that support "3 Mode".

Multi-Purpose:

• PCMCIA type 1 slot

The Marty's IC Card slot is compatible with type 1 PCMCIA cards, including battery-backed SRAM cards (accessible from the BIOS menu) that can be mapped to a drive letter and used as a small drive. Fujitsu also officially released a PCMCIA 2400 bit/s modem (FMM-CM301) for the FM Towns Marty. This modem was bundled with the special TCMarty that also came with a printer port. While it is widely believed that the IC Card slot can be used for RAM expansions, this is not correct.

Controllers:

• 4-way D-pad, A and B buttons, Select, and Run, as well as an extra button above the two "face" buttons
• 2 standard controller ports
• Keyboard port

The controller connector is a DB9, referred to as an "Atari Type" in Japan because it's fundamentally the same connector as an Atari 2600. The Marty's Run and Select buttons are the equivalent of pressing right and left, or up and down at the same time. A six-button controller from Fujitsu was available for use with Capcom's Street Fighter II. Capcom also released an adaptor for their CPS Fighter stick which made the stick compatible with the FM Towns/Marty as well as the Sharp X68000.
