This 1982 computer was designed in part by Chuck Peddle. Chuck Peddle is the inventor of the MOS 6502 CPU which he first used on the MOS KIM-1 and later used in the computers of Commodore (VIC-20, 64 and PET series), Apple (1, II and III ), Atari 8-bit line, Acorn 8-bit line and many more. In 1980, he left Commodore (which MOS took over) to start a new company, Sirius Systems Technology.

The Sirius 1 is based on an Intel 8088 5MHz processor and has a whopping 128K memory (up to 896K). It runs CP/M-86 and MS-DOS. In Europe, especially in the UK, they were sold by ACT and sales were good enough for ACT to develop their own computer, the ACT Apricot.

By the end of 1982, Sirius was selling 2,000 computers a month. But competing with big blue (IBM) was not possible. Also, the Sirius/Victor was not compatible with IBM. Some say it's technically a superior machine with much higher storage capacity on 5.25-inch drives (1.2MB on a single-sided drive, 2.4MB on double-sided!), higher-resolution graphics (800x400), and even a display with 80 or 132 columns.

This meant that, even after the name change to Victor, the company ran into financial difficulties in 1983 and filed for bankruptcy in 1984.
