Well, I finally got my paws on a nice EISA memory card that takes 30-pin RAM, which I now have an abundance of! So I figured I could now see how much RAM I could cram into my PC AT...
I thought I'd start off with my main selction of RAM to begin with: 8 sticks of 9-chip (pairity, right?) 1MB SIMM's; the maximum my Boca card could handle. My system will actually count up the RAM, right into the 8 or 9KB range before it gives me a pairity error. Same thing with any other of my 9-chip 1MB sticks, and with any other sticks of RAM (3, 2, and 8 chip) the system won't even count the RAM.
Almost the same thing on my IBM extended memory card (3MB, max.). I currently have 2MB - 2 sticks of 1MB, 9-chip - installed, yet when I try any other combination of RAM, with or without the working 2 sticks, it wouldn't count up any RAM aside for what's on the motherboard and 128KB base memory card, 640KB.
This really has me scratching my head, as I have tried almost every combination of RAM and I can't get anything to work aside from the 2, 1MB sticks in the IBM memory card. The only thing I know for certain about all of this is that the system archetecture requires pairity RAM to operate.
Any thoughts?
