I've had this board in my box of S-100 boards for a long time and haven't
gotten around to fixing it, so I'm going to sell it as-is for what I paid
for it ($50). This board is basically a follow-on to the Morrow
SwitchBoard, it uses newer devices and is IEEE-696 compatible.
Unfortunately, someone pulled the PLD/decode ROM, so it doesn't currently
work. I've powered it up on my test backplane, regulators and capacitors
are good. The manual is available online and documents which pins on the
PLD/decode ROM do what, but IIRC it doesn't include the equations for it. I
believe one could replace it with a sufficiently high speed ROM, or build
an adapter and use a GAL. In any case, it's sold AS-IS, and definitely
won't work if you just plug it in and expect to use it!
Contact me off-list if you're interested. Price is $50, shipping in the US
is $12, overseas is probably going to be $25-30.
Thanks,
Jonathan
