    Is that the only harmful aspect of welding light? I assume not, because if it was you could look at it through even a dinky pair of drug store sunglasses right?

    Having TWO DHCP servers on the same collision domain is an abundantly bad idea. No one is suggesting you disable the one in your router, just the second, spurious one

    IMO you should try the xtal swap anyway. The SCAMP chipset was only rated at 25MHz in 386 applications sure, but that doesn't mean it won't work with a 25MHz 286

    As for storage, I did a thread about the best options for a fast 286 a while back. Tl;dr 10kRPM SCSI is the best with a bus mastering HBA

    Yes, people were in fact expected to swap xtal oscillators with CPUs back then. The second one is probably for a math co processor, I don't think there are any 287s that will run above 16MHz

    If the generic IDE card doesn't pan out you can grab any of dozens of those types from Ebay. Or you could grab an IBM MFM combo card for around $20-40 if you want to get it back to factory.

    there were displays which accepted analog RGB which had a DE-9 input?

    I've seen many early VGA adapters that had both 9 and 15 pin outputs, but the 9 pin was always for TTL RGB, so I thought

    The X1 line suppression cap in my 5154 exploded, as they often do, but there was nothing wrong with the electrolytics. Your X1s are still clearly unexploded
