The UNIXpc Reference Manual (the one with the schematics, etc) and the UNIXpc EIA/RAM Combo Board Installation Guides both contain a set of charts and tables describing installation of such accessories. Assuming your CPU has 0.5MB on the motherboard, there are only TWO combinations of installing a 1.0MB EIA/RAM card and a 0.5MB RAM card per: +--------------------------------------------------+ | | | BACK OF UNIXpc | | | +--------------------------------------------------+ | +------------+ +------------+ +------------+ | | | SLOT 1 | | SLOT 2 | | SLOT 3 | | | +------------+ +------------+ +------------+ | +--------------------------------------------------+ I. The 0.5MB RAM card *MUST* be in slot 3 II. The 1.0MB EIA card can be in EITHER slot 1 OR slot 2 That's it. The docs do NOT show any other valid combination or permutation.
