UX A1500/2500 etc are just A2000 machines so don't count.
A1000s are very thin on the ground for sure, probably because nobody wants to sell them at their undervalued sale price.
They do count if they vary in any way in appearance or build, and that could also mean in the form of dedicated peripherals and or even the box. Collectors of stamps want the mint, fine used, gutter pairs, traffic light gutter pairs, sheet, presentation pack etc and yet technically all the same stamp. That's what collecting is all about. I spent like an eternity trying to get the cheese for the modulator for the 500 and the stick end for the Enterprise. The sellers were amazed that I didn't want the computer and I just wanted the packaging. Interestingly the box is worth way more than the machine sometimes. Cus people throw the boxes away.
Here are three computers that I was given ' GIVEN ' last year. You can pick up the common makes no problem, though the lesser known models are tricky.
