I am trying to upgrade my Zip GS to go 12 MHz. I have replaced the Cache with 15ns fast static memory. I have also replaced the CPU with the 14MHZ one. I have tried 50, 48, 40 and 36 MHz OSC but the only one that will work is the 36 MHz. Is there something else I have to replace to make the Zip go faster then 9MHz? Thanks
