link: http://www.ebay.com/itm/272662031085 This board had a dead 8088 CPU, which was replaced with a similar ceramic AMD D8088 CPU. It has, at some point in the past, been modified to support 640K RAM (a common mod for 256K boards) -- this can be reversed by removing an IC and a jumper. Fully tested as stated in the listing Fully assembled and tested XT-IDE rev 3 boards are available for bundled purchase with this board -- your XT-IDE will be tested in this exact board. Thanks, Jonathan
