I recently was given some Intel iSBC-012CX memory cards. These are 512K ECC DRAM cards that support both Multibus and an auxilliary high speed memory bus on the P2 connector (iLBX?). There was also a version that omitted some components and didn't support the aux. bus; I think that was the iSBC-012C. There were also partially populated models with 128K and 256K capacity; I think those were designated iSBC-028C[X] and iSBC-056C[X]. Anyhow, I'm looking for a manual for these boards, or at least information on jumper settings. Multibus originally only supported a 1M address space, so two of these would fill it up. Later A20-A23 address lines were added, but they were put on the P2 connector. Thanks! Eric
