But: You don't need all that stuff. I have yet to see an ISA card where you can't just apply the simple rule that components are always on the A side, so if you orient the components on the same side as a regular card, you are good to go. On the other hand, I did already see "ISA" cards (extra- …

Think its called LIF, as in Low Insertion Force. So it shouldnt take much force, tho if its been in there for a long time it …

Cannot tell by your pictures. Some MX440 used a NV17 with 128bit memory but not all. Think the GF FX5500 would be a better match to a P4

Have you run any memory tests on those sticks? Memory problems can cause all kind of weirdness. My guess is NO :) A lot of boards will downclock the memory if all slots are filled. Some don't like it at all. Anyway, how is swapping 2x2 to 4x1 an "upgrade"? Totally agree ! Running 2 versus 4 for …

There is a reason it burnt. Maybe bad caps, bearings/motor failing, shorted heads or ?? drawing more power than the amp can supply. Need to find why it burned out.

Horun, well I'm pretty sure you couldn't run these Cyrix FPU's async, so to get 33 Mhz out of the FPU, the CPU would also be running at 33 MHz, meaning it would be upgrading a Harris 16 MHz 286? User Anonymous Coward knows a lot more about 286 upgrades than I do, perhaps he will chime in. But the …

Have you tested the VS350 with a ATX voltage tester or DVM ? It is possible it is bad or when the old PSU died it did something not good to your CUBX board.

This is pretty niche, but since this thread's a repository of all things AudioPCI, then it might as well be here. A year or two back I picked up an AudioPCI 3000 but unusually, it came with a separate "power amplifier" board based around the LM1876TF . Excuse the crappy better-than-nothing phone …
