For an explanation of the difference between PS/2 SIMMs and Industry
Standard SIMMs visit Louis Ohland's
Memory Identification page,
extensive list of many part numbers for PS/2 SIMMs can be found on his
Memory Reference page.
Below is a short summary of the IBM PS/2 SIMMs that I have found applicable
