The Actrix computer, released in 1983 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 (later Actrix Computer Corporation), but both the company and its product changed names after trademark disputes.[1][2][3]

Access Computer

Access Computer was the common name for the Access Matrix, a transportable personal computer introduced in 1982 by a United States computer company, Access Matrix Corp (AM CORP on FCC documentation).

Hardware

The Access Computer had dual 5.25-inch floppy drives (either 320k-DS or 168k-SS) a detachable keyboard, a 7" built-in amber CRT monitor, and a built-in 80 CPS Epson MX80 dot matrix printer with GRAFTRAX-80 chipset. It used the CP/M operating system, and also included a Bell-103 300baud modem with both acoustic-coupled and direct connections. Additional connectors for IEEE-488 (external hard disk), composite monitor, RS2-32 serial and Centronics parallel were provided. The mainboard has a 50-pin header designed to support 8-inch disk drives (4 heads on two double-sided disks - drive letters C:/D: and E:/F:)

Software

Access Matrix came bundled with MBASIC, CBASIC, the Perfect-series office software, Personal Pearl database and Fancy Font markup/formatting system. Custom-written software included a disk format/verify/duplication utility (DISKU.COM) that worked with both the internal A:/B: drives as well as optional external 8" disks (C:/D: and E:/F:). A custom-written Telecommunications utility (TELCOMU.COM) offered dialup address book, basic terminal emulation, XMODEM/Modem7 file transfer and other features for connection to BBS and other online systems or to operate as a drone to receive files uploaded from other computers.

Market

Although not truly portable the all-in-one design did allow for quick setup and shut-down. It was rugged and although weighing 15 kg, it was reasonably easy to transport in a car or in an aircraft's coat- locker. The Access Matrix had option of a padded cloth bag with shoulder-strap or a heavier-duty leather/cloth bound protective case with carry handle and shoulder-strap.

Apparently the system was popular with journalists who could use the inbuilt "OFFLINE" type-writer mode to create and print simple ad hoc single-page documents ready for immediate faxing to HQ from their hotel lobby. Another option was to combine the word processing and telecommunications features to create a document using the word processing software and immediately upload the document directly to either an online services such as CompuServe or indeed to another 'waiting' Access Matrix at their head office.

Actrix computer

The rebadged Actrix DS was presented at the Las Vegas Comdex in November 1983. There was another model called the Actrix SS with a 170k 5.25-inch disk drive.

Options

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

In Australia, one official distributor of the Actrix Computer range was Richard Carpenter, based in Little Mountain, Queensland. It is believed 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.

Failure

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.
