I think it was also badged - perhaps with a different interface - as the Commodore 1084. It kind of took over from the BBC Microvitec Cub (15kHz, TTL RGB) as an early Archimedes colour monitor. https://blog.roberthargreaves.com/2016/04/16/cm8833-repair I have a Logica VTS Kennet 2400 from about 1985. It was an MS-DOS machine when those could exist without being PC-compatible. It also had SASI : the interface isn't much more than buffer and latch, but formed the basis for SCSI. We used either a Xebec controller or Adaptec. with ST506 discs. It's a very simple interface, a subset and predecessor of SCSI I think. I have extensive manuals for the machine which include the SASI interface and the command set. I did have a SASI controller on it at one time - it might still be there.
