each bank of memory has all the same memory module, the 64MB modules in bank 0 and 32mb in bank 1. Bank 0 uses Toshiba THM364020BSG-70, and Bank 1 uses Toshiba THM3620C0ASG-70. It seems like the memory and hard drive was the only thing messed with by whichever previous owner

Basic JEDEC pinout looks fine to me:

The only thing that's odd is the actual signal pins aren't in the same order. These modules are labeled as PS/2 type modules but I don't believe they actually are special IBM PS/2 SIMM modules. Because there's since presence detect is in the right place.
