Brian, Hi ... where/when you get the 14MHz CPU ?!?
They can be ordered directly from Western Design Center. I picked up a couple several years ago for this exact application. Unfortunately, my GSX won't even run reliably at 12.5Mhz. :-(
Brian escreveu:I have a Zip GSX card with the following components: 64Mhz crystal, 74LSO logic chip, 14Mhz CPU, and 32k cache memory (using two 6" RAM chips and two 3" ones). It works fine, but I want to upgrade it to 64k cache. But when I upgraded the cache to 64k (and adjusted the dips accordingly) the system doesn't turn on, just makes some beep noises). When I downgrade back to 32k it works fine. What do I need to do to get it running at 64k?
