If this link works for you, this is to an auction someone has for a bunch of IMS and other S100 cards. http://www.ebay.com/itm/IBS-Slavenet-P-N-710525-128B-Rev-D-1984-S-100-CPU-C… I linked off something called IBS Slavenet, but it also has a number of IMS boards IMS-Z-80B-Master-Slave-Board-A1270-Rev-F-1984-S-100-CPU-Card-Board-66-/ http://www.ebay.com/itm/192142950358 I used to buy the IMS 16K static boards as they were golden back when I ran S100, and had one of their Z80 boards, but stuck with mostly Tarbell and 8080 for my time with S100 and never graduated to this sort of system. Might interest those still doing S-100 thanks Jim
