I have a TransWarpGS with rev A GALs and a rev 1.5 ROM. It came as
7mhz with an 8k cache. It was pretty unstable when I recieved it, so I
put in a spare 14mhz 65c816 I had which stasblized it. Since I had a
lot of rectangular oscillators from my ZipGS upgrade experimenting, I
made up an adaptor so I could use them in the TransWarp. With those
two changes it's running at 14mhz.
