Jinx, as others mentioned, stick with ISA for your application. I was looking for an alternative to the parallel port for in-house testing. ISA cards are trivial to design but the slots have all but disappeared in newer systems. I was going to do a PCI board using the Lattice Semi CPLD reference design but it's a `timing and testing nightmare'... Since this is just a one-off project I decided to look at USB in the long term. In particular, I've been looking at Cypress' EZ series and another product that included the above on a small PC board. They provide the PC drivers. - Tom At 14:41 09-11-01 +1300, Jinx wrote: >> Overall, barring strong reasons to the contrary, I'd go with an 8-bit >> ISA board.
