We've got some truly ancient Unibus boot-ROM boards that use 1702 EPROMs, which is no fun because those chips are so old that it's not easy to get them reprogrammed. Hacking the boards to take (say) 2764s instead is possible, but the pinouts are so different that a lot of rewiring would be needed, and our overworked electronics man is not happy about this. So... Does anybody know of a decent Unibus boot-EPROM board? What we want is just a standard Unibus board with a couple of sockets for 2764s, with a bit of flexibility about where the stuff appears on the bus and how much of it appears. There's no shortage of such things for Q-bus applications, but we're a Unibus shop. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
