New CPU Accelerator options for 68K Macs?

if @max1zzz could work his sorcery and produce a 33Mhz one
Well I expect it would require changes to the GAL code, though it would be interesting to just stuff a 33mhz clock onto the card and see what happens!

I'm interested in what that EPROM is doing, most of the other cards of this type seem to not have one

I see an AMD logo peeking out behind the stickers on two of the GALs so they’re PALCE20V8s and won’t be crackable with the GALdurino that max1zzz is using.
I can have a look at them if we need to read them.

I have a programmer that will read unprotected PALCE IC’s but if you have a way of reading protected ones i’m sure we can get the card sent your way (and i would also be intrested in knowing how it is done)

Soooo, you still up for looking at the PAL's?
I have dumped U1 and U3 (a GAL16V8 and GAL20V8) but U2 and U7 are indeed PALCE20V8's and are read protected
