Sinclair PC200

Any of you UK based (and why not others too) Amibayers familiar with the Sinclair PC200?

While it was technically inferior to A500 and even Atari 520, the case design might have possibilities for a micro-ATX or mini-ITX mobo.

Yes I have one with matching monitor. I wouldn't butcher any of my old machines by adding a modern motherboard.

I think they're reasonably rare aren't they?
