I have both a CQD-220/TM and a CQD-220A/M/T here. There are a
bunch of PALs on them...If I can figure out which one is the address
decoder, my Data I/O 2900 may be able to read it. I am preparing to
move house at the moment, so I won't be able to look into this for a
few weeks...but if someone reminds me in late January I can take a
whack at it.
