Computers (Walter's Ash HP14)

I am now retired and my hobby is collecting, repairing and restoring old computers. The older the better! Broken and not working? I still want them! Also any computer parts you no longer want would be useful. I can collect upto 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, Amstrad, IBM, Sharp, CP/M Machines, Early pc's (8bit / 16bit era XT AT 8086 8088 80286 80386) And many others...

Also any floppy disks,floppy drives, add-on cards or parts ect are allways useful.

Thanks Dave.
