    SIMMS for 486 computer

    My sister has an older Compaq desktop that uses the old 72-pin SIMM memory sticks. Her computer still has the 14 MB or RAM that it shipped with (yes, 14--an odd number but it appears to be built into the motherboard). I have two memory sticks that once served in a 486 computer that I no longer own, and I want to give them to my sister. Before I jam these things into her machine, I'd like to figure out what I have. One stick appears to be bigger than the other--it has more little black chips on it--but I don't have a clue how to read the information printed on the sticks. For example, printed on the larger of the two: "PHY 36200078-24T." Anyone know what that means? Or can someone direct me to a good source for translating this stuff. Thanx!

    The information on chips varies enormously. Typical data can be a part number, date code, country of manufacture code, speed, generic part number etc.
    The fact that one board has more chips than the other may mean nothing other than that the one with more has smaller capacity in each chip, so they are in fact the same.
    If you can post the full text - and a description of any logo you may see - I'll see what I can find out for you.

    Did the two SIMMS you have originally work together in the 486? If they were originally paired together, there's a good chance they will work together in the Compaq. If they don't, chances are you won't even be able to boot; in which case, take them out again. It shouldn't hurt to try.
    We never really grow up, we only learn how to act in public.

    Here's the text that appears on the small paper sticker on each stick:

    Stick #1: 362007 S51T18JC Made in USA (Most of the individual chips bear the Panasonic USA label and the number 9634MA 098). The "PNY" logo appears on the green plastic base of the stick. On the reverse I see "GSEP-MO1" and "94V-0."
    Stick #2 (the "larger" one): PHY (maybe PNY ? Hard to say) 36200070024T. On the reverse, I see "W7595" and "9531."

    Thanks for any help you can provide!
