On the subject of hardware, I'd like to pass along a link that
details my efforts to clone three PALs--the AT&T 6300 video display
card HAL10L8; the Soundblaster 2.0 upgrade PAL16L8 and the Trantor
T130B SCSI controller ROM address PAL16L8.

HAL-%28Part-1%29
I don't know if I'd stick with SSI TTL for the "brute forcer", but it
worked well enough. I'd probably just use a cheap microcontroller if
I were starting afresh.
This appears to be a valid approach for pure combinatorial PALs and
HALs. Registered devices are a different matter entirely.
