Sirius Systems Technology was a
Chapter 11 protection from bankruptcy before the end of 1984. The company's assets were acquired by Datatronic AB, a Swedish software/hardware distribution company headed by Mats Gabrielsson. Gabrielsson signed a distribution deal with Kyocera, which began to supply PC
clones to Victor.

The Victor 9000 (distributed in the
Mannesmann Tally whom Chuck had met while negotiating an OEM
deal for printers.
The Victor 9000/Sirius 1 ran
group-coded recording (GCR), allowed standard floppy disks to hold more data than others at the time, 600 KB on single- and 1.2 MB on double-sided floppies compared with 140–160 KB per side of other machines such as the Apple II and early IBM PC, but disks made at constant bit density were not compatible with machines with standard drives.[5][6][3] The Victor 9000's 800x400 resolution screen (based on a Hitachi 46505 CRT controller chip - equivalent to a Motorola 6845),[7] 896 KB of memory (RAM), programmable keyboard and character set were also far ahead of the competition.[3]
While unsuccessful in North America, Victor 9000 became the most popular 16-bit business computer in Europe, especially in Britain and Germany, while IBM delayed the release of the PC there. Its success led to the
ACT Apricot.[8]
ACT outsold the Sirius/Victor subsidiaries and also led the way in proving that application software was the key to sales. Most sales across Europe went through small systems houses rather than computer shops.
The Victor 9000 was also distributed in the UK under that name by DRG Business Machines in Weston-super-Mare, who dealt with Victor Technologies in the US direct. It was not a particularly successful venture as ACT had already established a brand name and a loyal dealer base.
Reception
BYTE called the Victor 9000 "an excellent microcomputer with an outstanding array of standard features". It praised the high-quality video and large array of software available from Victor, while criticizing the high price of peripherals compared to the many third-party options on the IBM PC.[9]

[…] Track density is 96 tracks per inch, and recording density is maintained at approximately 8000 bits per inch on all tracks. […] The VICTOR 9000 uses an encoding technique called group code recording (GCR) to convert the data from internal representation to an acceptable form. GCR converts each (4-bit) nibble into a 5-bit code that guarantees a recording pattern that never has more than two zeros together. Then data is recorded on the disk by causing a flux reversal for each "one" bit and no flux reversal for each "zero" bit. […]
- ^ 96 TPI[…] Double-sided floppy drive offers 160 tracks at 96 TPI […] Floppy drives have 512 byte sectors; utilising a GCR, 10-bit recording technique. […] Although the Victor 9000 uses 5 1/4-inch minifloppies of a similar type to those used in other computers, the floppy disks themselves are not readable on other machines, nor can the Victor 9000 read a disk from another manufacturers machine. The Victor 9000 uses a unique recording method to allow the data to be packed as densely as 600 kbytes on a single-sided single-density minifloppy; this recording method involves the regulation of the speed at which the floppy rotates, explaining the fact that the noise from the drive sometimes changes frequency.
