My father surprised me by mailing a couple of links to 'old home computer' sites. The Obsolete Technology site, which fails to mention the Dragon 32, which I had for many years. And World of Spectrum - although I never had one. I think it means that he's clearing the garage. So anyone in the UK want a ZX-81, Dragon 32, or, I think, a Commodore Pet? ;)
I guess he missed old computers, vintage computers, our local computer history museum (which I think also lacks a Dragon), and the computer exhibit at Bletchley Park (I last visited there about 10 years, ago so can't say whether they also neglect the Dragon! ;).
