Ergo, wait states - something that I don't want... The original article of this hasn't wandered into zoo yet -- either we've got a propagation glitch or it had illegal headers and never made it -- but insofar as I understand the problem out of context, have you considered a faster TTL family like 74F? 74F is probably going to be less hassle than getting something like a PAL blown. -- And the bean-counter replied, | Henry Spencer @ U of Toronto Zoology "beans are more important". | henry@zoo.toronto.edu utzoo!henry
