The second is about an Ithaca Audio IA-1010 S100 bus
card.
I foud it between a lot of S100 stuff I had in a pile for
almost 14 years untouched. Strangly enough it was inside
a Jade Z80 Kit box, including all docu for the Z80 card,
but nothing about the IA-1010... It's hatd to belive that
it might be some kind of sound card, since there are no
connectors other then the Bus connector. So any information
would be apreciated.
It is a Z-80 cpu card. (There should be a Z-80 in the middle
area of the
board). The other larger chip is an optional 2708 eprom. As Allison said,
don't know the previous history of Ithaca Audio in audio electronics. It
uses an 8224 clock gen on the upper left, so requires a 18 mHz crystal for
2 mHz clock or 36 mHz crystal for 4 mHz clock!
