It kept the time, but the time did not advance, correct? The CMOS data can stay powered by the caps on the board for some time. The RTC isn't working without a battery, however, so the time stored in the CMOS is frozen.

Decided to fully recap the ALS100 and it ended in disaster. It became mono, and even noisier than before. All because I soldered a capacitor wrong and wanted to correct that before testing it. The result? The capacitor came off ALONG WITH THE FUCKING PAD! Just how cheap are these things!? Sorry to …

Not much today yet. Created this shim to allow stacking two PS1 consoles without causing scratches.

On a 300 MHz Pentium II with 128 MB RAM, Windows 2000 runs ok. I have it installed on a TECRA 8000. More RAM doesn't hurt, but it depends on the software you want to use. Also, you can disable many services you don't need to save RAM. The PPro-200 itself is certainly fast enough.

Optically I cannot see anything wrong with the firtst card. I mean it was still in blister and looks fresh out of the factory... It would be very helpful if one could *see* that a piece of electronics is faulty. But you can't. No matter how perfect it looks, it can still be dead. Also, what do you …

I did encounter this problem with a Plextor Premium CD-R drive, though this model does not employ a belt (IIRC). In this particular case, either the rubber ring on the disc spindle motor or its counterpart that fastens the disc from above (don't remember exactly which one) got sticky over time. " …

It's anti-flame coating. First one most likely carbon-based, second one is bromide-based. Believe it or not. It's completely silly (sorry) to even think this is for shielding. That part is mounted in front of a steel case which is already heavily shielded by itself. Yes, there were a few computers …

I bet it is some kind of conductive paint to create some kind of Faraday cage... Can anyone confirm? No, as it would not work in these two examples. For shielding, conductivity must not only be quite high (nothing a thin layer of paint could do), it also needs connection to all other parts of the …

Yes, very common problem. When in storage for a very long time, the belt gets stuck in its streched position (you'll see it's no longer round when removing it) and slips over the wheel that should drive it. Sometimes the tray may still manage to open, but not reliable until you replace the belt.
