I can't tell if that 3-pin header between the missing battery and the keyboard connector, above the middle capacitor in the cropped image given here, is an External Battery jumper or something else. If it helps, I uploaded a image of the full motherboard in another thread: https://www.vogons.org/ …

So if I buy a CR2032 socket and a rechargeable battery, it would work & recharge? Or do I have to buy specific socket …

Sorry to make another topic about this motherboard, but I've got a quick question about it and I don't want to derail the other thread, so... I recently got a power supply for it and the system boots up! However the CMOS resets upon every power up, (I thought the power supply would keep it saved …

Your model is the direct successor. Jetway replaced the 4 30-pin sockets by a single 72-pin socket (this is functionally equivalent), and replaced 3 ISA slots by 4 PCI slots (using the space gained by abandoning the 30-pin sockets). To operate the PCI slots, a 486 local bus to PCI bridge had to be …

Those are usually PCB (not motherboard, just the pcb house) manufacturer markings. 94V-0 means PCB is non flammable https://en.wikipedia.org/wiki/UL_94 . Im gonna guess TMF is board house and M21 code for particular process. Good to know; it makes sense that I see it on a ton of motherboards. This …

The motherboard I ordered for that 486 project I mentioned a couple weeks ago finally arrived. I can't use it right now–mainly because I can't buy that power supply yet–but something I'm not sure of is the model. The seller mentioned in the listing title that it's a "Jetway PV1.0", but searching …

Ah, interesting. Never used Visual Basic before. Good to know, thanks!

I decided to try this on PCem, this'll work perfectly for my 486 project; it beats sifting through confusing folders and filenames, that's for sure. I also really like the Windows 3.1-like GUI; I'm unsure if you programmed that part yourself or if you just used a pre-existing library, but it's cool …

Alright, good to know. I'll get the supply as soon as I can. Thank you!

It's an Athena Power AP-AT30; an industrial PSU made specifically for these older systems. It has the old P8 and P9 connectors (as they seem to be called) so it should be all good in terms of connectors.

I (very) recently started up a 486 project; basically I'm buying a bunch of parts online like the motherboard, graphics card, sound card, etc... all to build myself a nice 486 machine. Currently, I'm looking into PSUs; of course, you can't use a computer without a power supply. With all of these …

Hello. Did you test any other game to see if there are issues with the SBLive! driver (I assume that it is the WDM one that is installed) or it is just Hellbender? I tried Fury3 and Monster Truck Madness 2, and they seem to work just fine; even with acceleration on MTM2. I also remember trying …

(First post, please tell me if I did something wrong!) So I recently booted up my old Windows 98 machine again, and I decided to play some Hellbender. However, I've noticed that for some reason, the audio glitches out at multiple instances, and it gets even worse when I turn on hardware acceleration …
