Yes, it was one of those MS-DOS machines that wasn't a full IBM compatible -- another one briefly popular in the US and Japan was the Sanyo MBC-550 (or "Silver Box"). The idea was that people would write software that just used the MS-DOS API (the way they did for CP/M machines). But unfortunately they didn't -- most software assumed that it was running on an IBM PC so machines that didn't convincingly appear to be IBM PCs failed.

We (at the BBC) had the later 286 versions which claimed compatibility, and could run Windows 2.0 - they were still crap, and in fact so unreliable that we trashed them all and replaced them with Compaq, as doing so was so much cheaper in support, development and other costs.

Original reason for buying them was of course because they were "British". This was in the late 1980s - luckily things have changed since.
