Well, he gave me a patched CPU i.e. it has the wiring mods done to it and a compatible slotket apparently with it's own VRM. He sent pictures of it working including in Windows with CPU-Z. So I have no reason to disbelieve the guy. Anyways, yes -5V requirement sounds odd, but he's claiming he's run …

My MS-6119 BX2 v1.1 certainly doesn't require -5V. There might be different subrevisions of the v1.1 though. Read up some on Coppermine compatibility after picking up mine, and every source I could find clearly stated that the VRM on my board couldn't output the lower voltages needed, only v1.2 …

Usually just cutting wedges out of an eraser or something similar, and jamming them down between the CPU cartridge and whatever retention bracket came with the mobo, one on each side. Has worked well so far at least 😀

Got a Tualeron 1.4GHz in a Tualatin modded MS-6905 slotket in an Abit BH-6 board as main retro rig. Picked up a bunch of MS-6905:s when some German ebayer had them for sale at very reasonable prices. Works just fine, the only complaint might be that it's hard to find silent cooling solutions for …

Slot A and Socket A motherboards alike do sometimes have ISA slots, so Slot 1 isn't the latest! What is a good Socket A board with ISA that will run Athlon XP CPUs? Never came across one. You'd be looking for a KT133A board. My only personal experience of those is the Chaintech 7AJA2, which accepts …

Never disassembled one of those, so can't be sure, but judging from the way it looks, the rotor shaft is probably just pushed down in the bearing, and logically you should be able to pull it out and expose the bearing, with moderate force. Without knowing the bearing type, it's impossible to decide …

If the USB keyboard supports PS/2 through one of those "dumb" (no circuitry) adapters, you can just hack off the USB plug and solder on an AT one. If that were the case, why couldn't I just use a USB-PS/2 and then a PS/2-AT adapter? And even if that were the case, would it for sure work with an AT …

afaik 80 pin cables will be fine with slower speeds. They mostly just put an extra ground wire between each signal. Yep, correct. The only function of those ground wires is to reduce crosstalk between the signal wires, enabling higher data rates. An 80 lead cable - the connector still only got 40 …

IMO the K6+ CPU's are the best all rounders Probably yes, but it's time consuming and expensive to source parts for those systems. A Via C3 system is an alternative if you want that extreme flexibility. Slot1 boards, slotkets and C3 CPU:s are still quite abundant and cheap. You'd have to read up …

The modem most certainly got an internal rectifier bridge/voltage regulator, my guess would be an LM7805 or something like that. A 9VDC power source will work fine too. Depending on the regulator, you might even be able to feed it with lower voltages, and lessen the heat dissipation. You can always …

there's no reasons at all other than pure nostalgia ones to choose a P133 over a 233MMX, if you specifically want P133 speeds, just jumper the 233MMX to 110 MHz or something like that :) Quite the contrary, I would really want to get Pentium 233MMX - it is my dream CPU for real!

Using a home made passive mixer. Fits the "small and cheap" description perfectly.

Here's a tutorial with circuit diagram, it can easily …
