I have two major rules with old builds: 1) I try to use a CRT monitor if possible. Why? It's mostly because all of my older *somewhat* period correct LCDs either are dropping like dead flies or suffer from various problems such as poor upscaling. LCDs unlike CRTs need to upscale any resolution lower …

I belive twisting pairs would reduce crosstalk to a certain degree. As for fiber it's a whole other can of worms, but to me it's a viable option, though it can be a bit difficult to pass through (fiber doesn't bend as easily as copper, and in some cases excessive bending of fiber can cause breakage …

Looks like a RAM expansion board with two serial ports. I can't decipher the markings on the big chips near the bracket, a better picture of these could probably help.

FWIW, it would also be useless if the infrastructure doesn't have shielded cables in the first place

Could try putting a few drops of oil in the stepper motor (the black square thingy on the side of the drive), it could be that it's gummed up and can't spin freely.

It's like this cap is an offspring of those blasted RIFA smoke grenades (*ahem* filter caps that always love to go up in smoke), to be honest I never had a capacitor give out the magic smoke once. Either they went kaboom or silently inflated.

You need to flash them with a Mac-compatible BIOS (and since your model is probably one of the "Old World" models, it's going to be a bit difficult). Just like some people did to crossflash some PC GPUs for Power Macs G3s and G4s. EDIT: Woops, yeah nope. I completely forgot that the 6100/66 is …

They didn't really lose against PCAF per se, actually they won against PCAF, though they were asked to remove two paragraphs (I can't fully remember the specifics, but they did say that the tribunal recognized the quality of their research), I guess we could call that a tie.

I don't think it has to do with a bad contact on the board (as I said I tried bending my board a little bit, though not much in fear of breaking it, with how scarcer and scarcer Socket 7 boards are getting, I'd rather not risk my only working board). My board doesn't flex at all if I insert a PCI or …
