Spent the evening troubleshooting this 386 build. First, the 1.44MB drive stopped reading disks. Traced the issue to the I/O controller card. After replacing the card, managed to get disks working again. Immediately following that, my CF card suddenly stopped working. After further troubleshooting …

Socketed a PLCC32 bios chip. The same pin kept deosldering and crashing the machine 🙁 Now fixed, I needed a smaller tip I couldn't find.

I had a similar experience inside of a VAIO laptop. Have a loop at this "generous" thermal pad. This is on a Pentium 3 @ 600 Mhz. I found this after it died suddenly. Coincidence? 20221112_192235.jpg With what you are paying for sure you'd pay those 50 cents more for good thermal compound. I hate …

I've never trusted those little electric heaters. They always smell like burnt toast. I know it's just dust burning off the elements, but I totally wouldn't feel comfortable leaving one alone for more than a few minutes. And get this: I once had an old mid-80s heater whose power plug always got …

Save you time and MONEY. You really don’t get much of a Performance boost by increasing cache. At most maybe 3% to 5% Performance boost. Where you really will get a performance boost is by changing out the CPU. If your CPU is already Maxed out then I would try an Overdrive CPU Upgrade. The Only …

I wanted to buy some L2 cache and was going through my notes. Can't find any model (alixpress). I'm looking for 28 dip (and 32 for 128kb?) 15ns (or less but I guess difference is in price more than performance): 1) 32kb 2) 64kb 3) 128kb Any suggestion for models to look for? I tried the ones I have …

Update: Desolderded this MOSFET. 15V on the Drain (from power supply). The Gate and Source are shorted. Abnormal behaviour I presume? As you have the motherboard out, could you post high resolution pictures? This may help other users as it is not so common to get them (you need your laptop to have …

I have a GTX 690, 350W max power draw. It sucks juice pretty well. Gets hot, MUST have a well ventilated "environment" to avoid overheating. I barely use the rig hosting it. Getting these new cards requires a good case, fans and space. Old cards, 25W, even bad ventilation was ok. Not ideal but you …

My board, the dreaded Elitegroup ECS K7S5A (my copy works perfectly, knocking in wood), also doesn't (officially) support FSB66 and it doesn't allow the user to select that clock. Nevertheless, the clock synthesizer chip powers up with a default frequency of 66MHz until the BIOS reprograms it. If …

So as I suspected, the results with the 6.5x multiplier are similar to yours, so the CPU is really running on this multiplier. For comparison, I give the results with a multiplier of 12.5x. I don't know what's wrong with yours CPU and unfortunately you can't help yourself by interrupting fid4 with …
