Andy,
These are original Mark-8 boards with custom daughter
boards and custom (redefined) expansion bus. This was
a common modification made to Mark-8 boards as people
got frustrated with the original bus design. I don't
know why the crystal is missing, as the crystal wasn't
optional (the original Mark-8 in the Radio Electronics
magazine didn't have one, but those boards never made
it to production).
I have extra Mark-8 boards if you need them (originals
and copies from the artwork, I sold them on ebay a
while back) as well as all the spare parts necessary
to built one (to the original spec anyway), drop me an
email if you need some parts. I also can help with
technical questions as I have built 5 working Mark-8's
in the past 2 years, most likely though I probably
won't be much help with this heavily modified version.
