The problem here isn't the chips themselves, it's trading practices. Let's be honest - for the prices we pay for this sort of stuff, we can't expect anything other than recycled old parts. That's risky, but all part of the game when working with things that have been out of production for decades. I …

Yes, they are friction pop things (very technical term 😜 ), you should be able to just pull them out. If in doubt, push instead to avoid stressing the plastic.

Note that Intel So7 chipsets are limited in how much RAM they can cache. If you want to use >64MB, don't go for an i430VX or TX, and i430HX will only do so if you have a second tag RAM (not common in desktop boards). No L2 caching of everything above 64MB means subpar performance, particularly in …

Same applies to MVP4 as MVP3, so with 512kB L2 it can cache 64MB in WB or 128MB in WT mode. If you can set L2 cache to WT in BIOS, you can cache 128MB with it.

Steep prices, but the 90Z looks decent. Don't do the UV unless you have a UV chip eraser handy... Check whether your programmer supports it though...

Passive cooling of AT PSUs wasn't a thing, but might be an interesting project to do in case of compeltely overhauling/renovating a PSU. What you can easily do however is to replace the old, noisy, unreliable fan by a new relatively silent one (Noctua Redox is my current go-to option).

By "which microsoft did release them their self", do you mean "not IBM PC-DOS" or do you mean "retail, not Tulip or Philips OEM"? The Tulip and Philips OEM versions of MS-DOS 4.01 are pretty easy to find, retail could be more of a challenge...

AMI and Award. The retail BIOS is AMI, the Award BIOS is Packard Bell OEM. You have slightly more options in the retail BIOS, but some things from the PB Award BIOS aren't in there. Overall, I've not found a pressing reason to use one or the other. Do go for latest version of either for best CPU …

Could it be power draw? That underclocked P3 will probably draw less than the P3-450, all the others draw more. Check how hot the voltage regulators on the motherboard are getting. They might be the problem. Also, what PSU are you using? A Slot 1 system gets its CPU power off the 5V line. Old PSUs …

Did a bit of re-wiring of my retro setup. Last week I replaced my 'little' Edirol UM-550 with a Roland A-880. Now I also dug out its power supply. Bigger change was replacing the miniscule 5-port Zyxel unmanaged network switch with a managed 16-port one (Netgear GS116E). That's partly so I can hook …
