Interesting Old Computer Stuff

When I became interested in electronics as a teenager in Scotland, I used to read the excellent "Practical Electronics" magazine and I would obtain cheap components by ordering surplus or scrap "computer boards" that were advertised for sale in it. At that time such cards bore many discrete components, often with decent length leads, that could be easily unsoldered and re-used. Later on, the advertisers sent IBM SMS cards (follow my "other neat stuff" link below if you don't know what those are) which had shorter leads but could still be recovered, and, even later, useless integrated circuits appeared that could not be recycled.
I am still fascinated by old computer circuit cards, those with discrete transistors, for two reasons. Firstly, they are beautiful objects that show a technology that no longer exists. Secondly, I am interested in the earliest British transistor computers themselves, and want to save any remaining artefacts of that period from being lost. I have managed to accumulate a fair number of such circuit boards, and am proud to display them together with some information about their history.
Many of these boards were bought in two shops in Tottenham Court Road in London: Proops and Z.I.Aero Services. These were fantastic places for the electronics hobbyist: just piles of surplus and scrap electronics, you never knew what you would find there. Alas they are long gone. Now Tottenham Court Road and Edgware Road are filled with hi-fi and computer shops.
I have also managed to acquire this other stuff that may interest you if you like technology .... use the links on the left.
