Unknown Z-80 SBC

[saundby]

I've got a couple of boards for a Z-80 single board computer--one bare, one populated--that I don't know the identity of. Anyone here know what these are? More detailed images can be seen at http://saundby.com/electronics/unkz80.html. Thanks.

Looks like a Xerox 820, based on the Ferguson Big Board

I was thinking that, but the 820 I've got has a couple of card slots.
just checked on "oldcomputers.com" it's an 820. I have an 820-II

Nifty!

Thanks a lot. I suspected it was something of the sort, since it came with BB-Is, BB-IIs, and LB+s. But I'd never seen an actual Xerox board, and there are so many Z-80 boards out there...

I'll have to start poking around and collecting things for it. I've got several other systems already in train, so I probably won't have a chance to try bringing it up until sometime next year.

Thanks again!
