Computers Old or Faulty (Walter's Ash HP14)

I am now retired and my hobby is collecting, repairing and restoring old computers like the ones in the picture. The older the better! Broken or not working? I still want them! Also any computer parts you no longer want would be useful. I can collect up to about 30 miles around High Wycombe or further for interesting items. I am mainly looking for computers from the 70s 80s and early 90's like>

Tandy (Radio Shack),
Commodore,
Sinclair,
Apple,
Atari,
Acorn (BBC, Amiga ect),
Amstrad,
IBM,
Sharp,
CP/M Machines,
Early pc's (8bit / 16bit era XT AT 8086 8088 80286 80386)
And many others...


Also any floppy drives (especially 5 1/4 inch)
ISA cards (especially video cards)
Old hard drives

If you have any more modern computers Please let me know the model/make or maybe send a picture as I may still be interested.
I don't want laptops.

Thanks Dave.
