But there weren't too many Lisas (working or otherwise) when the thing came out!

Well OK, "a lot" can mean a lot of different things depending on context ;)

In the vintage computer collector/enthusiast scene, there are probably dozens of working Lisas. How's that?

Yep, I know about all that - I had big cupboard full of the damn things in my flat in london [various ataris (6502 and 68k based ones), dragon 32 (coco lookalike), peculiar IBM pc clones, and other stuff]

A few years ago I got my nephew to do up the flat for sale, and he junked the lot - at some point you have to get rid of things.

I will never buy anything except a laptop again.
