I think any of us that have dealt with older comps know eventually stuff needs replacing.
Other than eBay are there still shops that cater to us? If so, drop some links. I know I'm going to be on a search for a better SCSI drive for the LC 520 I just got. Worked at work, brought it home... HDD died
Atari 8-bit and ST series:
Best Electronics
B & C ComputerVisions
If you need parts, upgrade kits or anything else for your A8 or ST, both these shops are top notch. Not the best HTML design for the first link but solid reliable service.
Commodore Amiga:
AmigaKit
Great UK based Amiga shop which does shipping for Canada and the US too!
Anyone else got some good reliable shop links?
