- Must be pretty old! My 3 year old model had no problems with 4MB

- Not to be nitpicky or anything but SIMM refers to the packaging of the
- chip and the PS/2 modules are SIMMs by this definition it's just that
- they're 36-bits whereas the "standard" SIMM is 9-bits.
- Whenever I bought memory for mine I always specified "PS/2 memory
- module" but most of the companies know what memory your machine takes if
- you tell them it's a PS/2 model ##(sx), and it's not too old!
