You will find that as long as it is 72-pin (SIMM) EDO, it should work fine. SIMM modules came in a couple of types, 30-pin and 72-pin. Your are both 72-pin SIMMs. As far as I know, EDO was/is only available in the 72-pin variety (and not the 30-pin), so you should be safe. > By the way, is it difficult to upgrade the cpu?

You just unlatch and lift a single lever to loosen the CPU in its socket, pull it out, drop in the new one and push the lever back down into its latch. You will probably also need to remove the heat sink on top of the CPU, but that is usually also a pretty easy thing. As an example, my first Win95 PC had a Pentium 120MHz CPU running on a 60MHz front-side bus (FSB) with a 2x clock multiplier. If you don't see the relationship, notice that 60 x 2 = 120. Therefore, the CPU speed in MHz (megahertz) is always a product of the front-side bus multiplied by the clock speed multiplier. I later looked at the motherboard specs, and found that I could increase the FSB from 60 to 66 MHz, which would effectively also give me a 133MHz CPU speed (66 x 2 = 132, but in fact the 66MHz was really 66.6666..., so it comes out to 133 when doubled). Even later, I also noticed that I could increase the clock multiplier from 2 to 2.5 or even 3! This would give me yet another speed boost, from 133MHz to 166 (66 x 2.5) or 200MHz (66 x 3). I tried to change it with my current CPU, but the CPU itself couldn't handle that clock speed, and refused to boot. I then purchased a 200MHz Pentium, popped it into my motherboard, and wheeeeee! I had my 200MHz system running perfectly. Now, noticing that you are running a 200MHz CPU already, you will need to check your motherboard specs (often available from the PC manufacturer) to see if it can handle a higher clock multiplier and/or higher front-side bus speed. Chances are pretty good it will *not* be able to handle a faster FSB, but it *will* take a higher clock multiplier. Assuming this is the case, and that your clock multiplier is 3x, then if you can get it to 3.5x or 4x you should be able to handle a Pentium 233 or 266MHz CPU. I think 266MHz was the fastest Pentium that Intel made, but it is possible they came out with a 300 or even 333. I know the Pentium II CPUs started at 233 and went up from there, I just don't remember how much crossover there was in the speed (MHz) ratings between the original Pentium and the Pentium II.
