pictures: https://imgur.com/a/r5AN8wu 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
