I have a really neat Qbus card with a TMS9918 sprite-based video chip on it, though! Which one is that? I have a Matrox card and one of the VSV cards (can't remember which one) I don't know who made it; I will check. It's an amazingly simple board. The TMS9918 is very easy to use to begin with...All this board appears to be is the standard TMS9918 app note circuit with some glue logic to connect it to Qbus. It should be trivial to bring up and get graphics out of if I can find out where its CSR sits. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
