🤔 darn Someone else I thought found a data sheet for it at some point but I can’t figure out where that went. There was a old thread where I was asking about this but can’t remember where it went. What about some kind of adapter?

The atx to nc pins method seems like a good option. What wire should I get?

You could use bodge wires on the back of the board to connect all the +3.3Vcc pins and use a selfmade card with a DC-DC converter to supply +3.3V to the slot. But you could also put the converter behind the mobo and connect it to the wires directly. Maybe add a few capacitors for decoupling on the …

I’d like to get one of these. Any chance you could hook me up? Sorry, really don't have the time to make new boards now. Also, there is a high chance that the board isn't manufacturable at the moment due to the global IC shortage. If you want, I can send you a blank PCB and the schematics/BOM. That …

Why the need? 3.3v cards that require that voltage normally shouldn't fit into 5v pci slots, there's a notch preventing insertion. Universal pci cards shouldn't care what's the voltages there. I have a bunch of dual notch cards that I’m pretty sure aren’t working because of lack of 3.3v Atheatos …

I think they were actually for Socket370. I've only ever seen pictures of them. There was supposed to be a socket7 version, but I'm pretty sure that one didn't make it past engineering samples, if it even got that far. I’m really wondering if it’s possible to track down someone who might know for …

The main deal with K6-2 was 3Dnow, but that only made a difference if software was written to support it. K6-2 also benefitted from the die shrink on the 2nd wave of original K6 chips. I'm not aware of any other meaningful improvements. Slow slowest K6 was the 166 (originally only available as 166 …

Had a fun discussion on discord earlier, we were wondering about deets regarding the fabled Joshua core socket 7 MIII that never was, and the 370 MIII that only briefly was.

Has anyone ever come across any of the fabled mIII socket 7 cpus that were apparently never released? But were actually made in small quantity.

A 233 MMX can't saturate a Voodoo2 let alone a dual GPU card. It’s a dual 233mmx but that aside, I don’t disagree . I’m building for fun not for balance. That dual Rage 128 Pro card was the Rage Fury Maxx https://www.tomshardware.com/reviews/ati-rage-fury-maxx-review,156.html and predates Crossfire …

Wow, I don't remember seeing any k6-2 slower than 300. My first K6 was actually the 266 core shrink. I got that running 300, then 333 when I got braver. 350 wasn't doable on that board, but seemed to be after it was retired on another board (didn't work it very hard) ... mostly I think though the …

I would guess higher FSB might be feasible, but you're going to have to make sure you use PCI cards that conform to the 2.2 spec and have fast enough RAM. Because the PCI divider can only be set to 2, you need to run the bus grossly out of spec. Newer cards support 66MHz so should be able to handle …
