It would make more sense if you retrofit another 486 LPX board inside that Gateway, which actually has a real VLB slot on the riser, rather than struggling to tap into the CPU socket with adapters and make an unstable mess.

The missing resistor is used for the slow fan header. Owner of that 2nd image board on TRW 😜

Not all processors have internal pull downs. This is a misconception. I thought we were talking just MMX usage on a Socket 5 board. For others it will be different obviously. I’m pretty sure that Mmx is one of the ones missing a pull up. Above in a previous reply you said it was. Yes, I even said …

Given that it has an internal pull-down, it may not necessarily end up as 5V after the initial resistor mod (resistor ladder gets made), but it's better to play it safe. You can tell I'm very used to working with 5V TTL circuits 🤣

Sounds simple enough right? I just gotta solder a resistor to the BF0 pin on the back of the motherboard? Where would I have to solder the other end of the resistor to (sorry for my confusion) Just find any pin on the motherboard which supplies 5V. If not sure, you can grab 5V from the Keylock …

OK, I spoke too early. It was smelling very nice when I went to bed last night and I woke up to find that the stink had returned in the morning..

After fiddling around for many hours with this motherboard I think i’ve come to the conclusion this motherboard only goes up to 2x multiplier as it is … if I want 3x i’m gonna have to do some modification, but i’ve seen people modify their CPU to do the proper multiplier.. how is that done? This is …

You guys misunderstood the premise of this build! It’s supposed to be an experiment how far I can push a socket 5 system. My super period correct systems are my upcoming socket 7 build and the socket 370 pentium 3 build. I got the SB live out of my socket 462 athlon build since that motherboard has …

Thank you for the reply. I did a closer visual inspection yesterday. No traces seem to be damaged and there is no battery acid on the memory slots.

For you and others that claim about quality and stuff..

That is a very subjective take which I don't share, most drives …
