MACH 5
MACH 5 package front.jpg

MACH 5 by Access Software was available around 1984 and a follow up named MACH 128 was introduced to the market a little later. Like most speeders on this category the cartridge was well known mostly in the USA. We lately received MACH 128 dumps which sort of astonished us. So far only one usable MACH 128 ROM was dumped, but the cartridges we came across contained different MACH 5 versions. Slightly more info in the archive - nothing to get overly excited though.

Functionality

  • Fast serial I/O (1541 floppy disk drives, 1571 and 1581 with later versions)

Lord Crass tested this cartridge a little more excessively and even though the 1581 is not mentioned on manuals we found so far, it is supported by Mach5 v3a cartridges. It currently boils down to: "Only v.2A is compatible with both NTSC and PAL. Other versions are NTSC-only, except for v3.A, which supports 1571 double-sided mode and 1581, and is compatible with NTSC/PAL only with 1581. With 1541/1571 it is NTSC-only."

Missing

  • more MACH 128 ROM Dumps

Tech

Ripped again from mach5.c from the VICE emulator 

    This cart has 8Kb ROM mapped at $8000-$9FFF.

    The $9E00-$9EFF range is mirrored at $DE00-$DEFF.
    The $9F00-$9FFF range is mirrored at $DF00-$DFFF.

    a write to IO1 selects 8K Game mode
    a write to IO2 disables the cartridge


Binaries

Cartridge_Speeder_all_rr.c64.org.rar contains:

  • MACH-5 NTSC V.1A .bin and .crt
  • MACH-5 NTSC V.1B .bin and .crt in two versions
  • MACH-5 NTSC V.2A .bin and .crt
  • MACH-5 NTSC V3.A .bin and .crt
  • MACH-128 v1a and v1b .bin
  • MACH_128_Utilities.D64 - while the header says MACH 5 this disk came with the 128 version
