Isn't R276 related to some ISA irq? I also happen to have a ASUS PCI/I P54NP4, but this won't even boot to linux ... maybe something fishy. Yes, it's a collectors-thing - you have one, you're happy! And on some sun-moon-constellations, you get it out of the box, put in on the table, push some cards …

And that’s the psu side? Hi, yes I just took a photo at the end of the cable and inverted it horizontally so it matches the position of the 6-pin socket in the actual PSU. Unfortunately I don't have a multi-meter right now but eventually I'll measure it :) I'm just wondering if all the pins are …

Oh wait. You are saying that it’s a modular psu And that’s the psu side? Okay I think I get it. Plug it in and use a volt meter to see if it is putting out correctly. You reallllly gotta be careful with these, mfgs haven’t standardized the psu side and it can lead to tears. Alway confirm with a volt …

Good job :-) I’ve been playing with my 256kb modded 2+570 in mine recently at 400mhz. What socket did you use? AMP one from ebay? What video card will you use in the build? I assume you’re going for dual 233? Years ago i ordered some AMP sockets from ebay. They seem exactly the same as the tyan …

May need -5v So it turns on, then right off? (When you short the green and black) Any chance you wired up the switch to a momentary switch? It needs to be a switch that stays closed Many of those dual psu type mobos require you to change some jumper settings to use one vs the other Any chance you …

I’ve been testing with the at2atx device and haven’t been able to get anything conclusive between a 2+ 570 at 400 2.15v and a 3+ modded 570 at 400 2.15v The amperage is just jumping all over the place I think variations in heatsink temperature are causing more of a fluctuation in amperage than the …

I once used some copper electrically conductive paste on a CPU and when I went to remove the heatsink after a few months, the liquid was all gone but the copper had stayed and it had formed a bond between the cooler and the heatsink. It came off ok, but it was a bugger to get the copper layer …

On the K6-iii, might be worth looking at the pads in the top corners: k6iii_possibleConfig.jpg They're marked slightly differently, in a similar way to the k6-2+. My guess is that the pads marks with a single tiny dot are possibly Vcore, unmarked are Gnd, 2 tiny dots might be Vio (but they never …

I'm suspicious of the lower voltage and/or higher clocked K6-2 examples if they also have late date codes. The 1.9V CPU you opened is visibly different inside though. There's also a 2.0V rated CPU that's marked for something like 475MHz I think. I wish these CPUs were still dirt cheap in quantity. …
