Re: GAL's and PALASM
I'm not sure if it's too late in the day for this suggestion, but could the S100 80386 CPU clock circuit ( U15, U14 ) be implemented into one of these GAL chips
in order to reach the maximum CPU speed of the 80386.
The 16V8 datasheet shows these GALs to be way faster than standard logic chips (250Mhz 3.5ns prop delay)

Guy's just wanted to mention I have "see religion" in terms of using GAL's to simplify our future more complex S100 boards.
As we move to CPU's like the 80486 and higher it is clear the 74LSxxx chips alone will not fit on a single S100 board to carry out the functions of these CPU's. I have also concluded that I will need them for out ISA to S100 bus converter board and XVGA type video boards. These are all projects in the works and will probably not see the light of day for some months.
To expose GAL's to those that may not be fully aware of them, I have written up a short introduction here:-
