Actrix (computer) - Specifications



  • NEC D780C-1 (clone of Zilog Z80B) CPU @ 4 MHz
  • 64 KB RAM
  • Two 320 KB DS-DD floppy disk drives (Actrix-DS model)
  • or Two 170 KB SS-DD floppy disk drives (Actrix-SS model)
  • 7" amber CRT display
  • Epson MX-80 dot-matrix printer with GRAFTRAX-80 chipset
  • Bell 103 modem and acoustic coupler
  • Detachable keyboard

The void to the right of the two floppy drives can be either open, for convenient storage of a handful of floppy diskettes, or blanked up to conceal one of two options:

  • Intel 8088 co-processor board with 256 KB RAM and MS-DOS 1.25
  • Internal UPS

Another option is

  • Fitment of a 50-pin connector at rear of void for 8" disk drives

If either UPS or 8088 options are present the rear or the void is blanked off with a screw-on plate. If the 50-pin 8" disk cable option is present the rear of the void is changed to a clip-on panel securing the 50-pin cable connector. If no options are fitted the rear of the floppy void is a blank clip-on panel. If only the 50-pin option is present the floppy void is modified internally with a plastic jacket to prevent stored diskettes from interfering with the rear of the 50-pin header/cable assembly
