link: https://www.ebay.com/itm/272986862278 Picked this one up in a larger lot of S-100 boards. The address jumper area was a mess, the soldered wire links were removed and replaced with machine pin socket pins. It's currently addressed to start at 0x0000. This one has a pretty low serial number, from what I've seen the earliest boards had no serial number at all, but this one is the lowest out of the handful of 1K boards I've personally seen, which were all in the 400-500 range. I have it listed starting at $1 as I have no idea what it's worth. If someone desperately needs this particular board (i.e. based on the serial number) for their system, send me an offer off-list and I can end the auction for you. Thanks, Jonathan
