Commodore PC-10 (G80-0915). Pricing may be a little on the high side, but there is a best offer option so you might be able to get it for a more reasonable price. It does appear to be in very good shape at least. This is the AT version so you can use it with modern PC with an AT to PS/2 adapter instead of require protocol converters like all the other Commodore and Amiga MX models.
Seems the same seller also has a
PC-5 (G80-0499), but that one speaks Commodore specific serial protocol.
