The Actrix computer, released in 1984 by Actrix Computer Corporation, was a Zilog Z80-based transportable personal computer running CP/M-80 V2.2. It was initially released as the Access Computer, made by Access Matrix Computer Corporation, but both the company and its product changed names after trademark disputes.




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

Another option was a 50-pin connector at the rear of the void, for 8" disk drives

If either UPS or 8088 options were present the rear or the void was 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 were fitted the rear of the floppy void was a blank clip-on panel. If only the 50-pin option is present the floppy void was modified internally with a plastic jacket to prevent stored diskettes from interfering with the rear of the 50-pin header/cable assembly

  • WAKEUP – used at boot to set date and time and apply configuration profiles created using CONFIGU (1.03)
  • AMD – Set CP/M to use the 256KB RAM of optional 8088 co-processor board as M: 'ram-drive'
  • INSTALL – Actrix auto-command installation utility - allowed specification of a .COM file to auto-execute at cold-boot time (1.00)
  • DAC-DS – Dealer Acceptance Test – a diagnostic utility for dealers to quickly tests memory/clock, floppy disk, video, printer and keyboard (1.01)

International distribution[edit]

In Australia, one official distibutor of the Actrix Computer range was Richard Carpenter, based in Little Mountain, Queensland. It is believed[according to whom?] that Carpenter imported two or three Access Computers as sales tools and demonstrators, but shipped less than a dozen Actrix Computers. In 1986, two demonstrator Actrix machines were repossessed by the financier, NatWest Australia Bank.


Expensive TV advertising and constant lawsuits concerning the product and company-naming rights were drains on capital that speeded the decline and ultimate stop of sales of Actrix machines. Existing orders were filled by one remaining technician, who built the last remaining machines from spare parts.
