after some thought (and thank you for the comments), 1 SD/MMC and SPI interface have been added to the EOMA68 specification. as these pins are already brought out on the EOMA68-A20 CPU Card, there is no modification of the EOMA68-A20 CPU Card design required. only those people with the [first] A10 CPU Cards (of which there were only 5 made, and i have 2 here) would be affected.
