Over in this thread, people were talking about how PC-ATs appear to be picky about which kind of memory SIMMs that they recognize. Is there a definitive list of what types of SIMMs work in a PC-AT, or is it just a game of Russian roulette (ie: buy 1MB SIMMs on ebay, pray that they work)?
I know that some early model PS/2 machines (such as the model 30) needed to use proprietary IBM SIMMs. Seeing as my IBM Enhanced Memory Expansion Adapter is from the same time period, I fear that is also the case. However, the IBM documentation on the card doesn't say anything to indicate as such. But I'm in the situation (as the folks in that thread were before me) where the only SIMMs that appear to work in the card were the ones sitting in it when I bought it on ebay.
