I don't know about "around", but I have 2 or 3 assembled and working
boards (out of a total production run of perhaps 20 - can't remember
exactly). There are a couple of bare boards, but the problem here is
that I don't have the fuse patterns for the PAL/PLD devices. I'm hoping
that Rod didn't blow the security links.
Maybe it's time to drag out the device programmer and see if I can read
any of them.
What PAL types are they? Registered ones are tricky if secured
but the simpler combinational can be reverse engineered by feeding every
possible input pattern and recording the outputs. Then the equations
can be derived.
