How to read the "Product Name" forRAM modules:
Part#10100, 1 x 36-60 (12),(read as: "one by thirty-six, sixty"), this module is onemegabit (1), by (x), thirty-six bits (36), seventy two pin, parity SIMMwith an access time of sixty nanoseconds (-60), and twelve chips on the circuitboard (12)*. This is a standard four megabyte, Mb, (RAM qty column),parity SIMM.

Parity SIMMs have either 9 or36 bits, ( x9 or x36). Non-parity SIMMs have 8 or 32 bits, (x8 or x32). Eightand nine bit SIMMs, (x8, x9), have 30 pins. Thirty-two and thirty-six bit SIMMs,(x32, x36), have 72 pins. Sixty-four bit DIMMs, (x64), have 168 pins.

* Note: If the number inparenthesis is accompanied by the "Mb" symbol, the number will be representingthe capacity of the module.
Example: Part #15410 DIMM 8x64-60 (64Mb) is asixty-four megabyte (64Mb) module.

Now, if youknow what "type" you require, what part do you need?
Here's how:Find the point on the table where the "type", (x8,x9,x32,x36,x64), intersectswith the "size" ,(1Mb,2Mb,etc.), to get the description of the part you need.EDO SIMMs are usually x32.

What do thelittle numbers on the black chip mean?
The numbers identify the type and sizeof that particular chip. The following is a list of part numbers used by variousmanufacturers.
