Well if you have never been, a visit to Bletchley Park, home of the code breakers also houses the National Computer Museum and when you walk around you will eventually through up one or two interesting artefacts.
Obviously Sinclair products
and yes those massive boxes either side of the BBC Model A/B are 2nd 6505 processors ha ha
below is me by a CRAY
but by far is this little interesting thing, after Sinclair and Acorn passed their prime in the eighties, Sinclair being sold to Amstrad, Acorn eventually getting in to RISC/ARM chips, this yellow beauty was the last only one of two ARM machines produced but never left the Acorn factory, apparently.
Instead of badging everything on the outside like Apple, Microsoft even Sinclair, Acorn put theirs in on the inside on the case??
I did have a chat with one of the guys at the National Computer Museum about a possible future QUANTA project, so something to think about.
