I used to have a number of HLH Orion machines, which were superminis
(they ran BSD 4.2 / 4.3) made in the UK in the 80s and very early
90s. A friend of mine still has some, which I suspect may be the last
ones extant, and a mass of documentation & media for them. He's
retiring soon and needs to find homes for them.
I think they're historically reasonably interesting machines - I
suspect they may have been almost the last significant British
computer design, and the earlier model was quite an interesting
machine, with user-programmable microcode &c (the later model was, I
think, not so interesting, if a lot faster).
Does anyone know of any museum-type places which might be able to
offer them a home? They are still working (we think, he needs to turn
them on). I'm thinking of approaching the Bletchley Park people, but
I'm wondering if anyone here has any better leads.
