What are the top 10 rarest vintage computer bits you own?

[RetroAND]

For me, it's a couple of Sinclair ZX80s and two JR-100U computers - None of them really that rare.

I have some cool stuff, but still can't find some of the pieces I want like an Issue 1 ZX Spectrum.

So nothing before 1980... Not even a Tandy or an original Apple II.

Though one zx80 has a very nice zx81 upgrade that looks factory installed and the other is original.

And I have an IBM that with an IBM asset sticker - so an IBM IBM... OK, that's not that rare I imagine, but I thought it was cool.

What IBM?
