Hi everybody, I've got a 486DX-75 with an IBM 486 Blue Lightning System
Board. I've got 8 megs of RAM and I'd like to increase my RAM to 16 megs.
According to the manual I need two 4 meg SIMMS specified as 1MX36
single density SIMM modules. I bought two 4 meg, parity 30 pin SIMMS
(4MX9) and the pin arrangement doesn't seem to match my mother board
and I sent them back. The new SIMMS had one row of 30 pins, and the
mother board looks like it needs a SIMM with two in line pin segments with
36 pins in each segment with a small space(about 1/4") between the two pin
segments. At this point I'm thoroughly confused and my questions are.
       1. Did I do the right thing in sending the SIMMS back?
       2. Are there different configs of 30 pin SIMMS?
       3. If the answers to 1 & 2 are affirmative, where can I get SIMMS for my
          board?

I hope I've stated my problem clearly, thanks a lot.
