Ohh Dragon 32... I used to sell those, along with all the other 8-bit contenders in a computer shop.
Actually, I don't recall selling a single one - all the kids wanted was a 48K Speccy. I recall it had a reasonable keyboard, and my brother in law used to get my wife to type in the games as they had one. Hmm, I wonder what became of it?
Fast forward 25 years or so and I have been collecting 80's micros. I've got a BBC B, ZX-81, Speccy, Electron, UK-101 (home made clone), Memotech MTX512, Atari ST, STE, Mega ST4 (x2) and a TT030 (which has just been sold). Would love an Einstein but they go for too much money.
Best place for cassette recorders is going to be eBay (maybe charity shops), but they seem to be expensive for some unknown reason, and I guess often have slipping belts or other age related illnesses.
