link: http://www.ebay.com/itm/272117827487 Tested, working, very clean except for a lifted topside /QB pad between ICs P and T, which doesn't affect operation since the trace connects on the bottom side. I don't know why the original builder chose such a large ceramic capacitor below the -8V regulator...let me know if you'd like it replaced. This is a REV 1 board with solder mask and a DIP switch for address selection, as opposed to the wire jumper address selection on REV 0 boards. I tested this one with several EPROMs on my IMSAI 8080. It generates wait states properly. It is currently addressed for 0xF800 - 0xFFFF. Thanks, Jonathan
