This an example of a BBC B built into a metal case with disc drives by Viglen - here 2 x 40 track drives. I bought this in Mar 14, the last time I saw one was 30 years ago when i debated buying one (nearly £2000 I think); I eventually bought a Torch System to go with my existing BeeB instead (that was over a £1000). The game it is currently playing is Repton.
If I am programming on the BBC B this is now the machine I use, it already came with a Watford Electronic 32k memory board and I have moved across the Acornsoft Basic Editor ROM from my BBC B, which after 31 years service has been shelved in a place of honour.
