....just my general observation, something else is awry... there's too long a literary of different things not working properly, and for mine (apart from win98) the only thing they have in common is PSU ~ have you checked the voltage rails are on spec? The other thing I have to say, is that I'm ... …

The sound card I'm using is, I believe, a Turtle Beach Montego A3D, and I don't remember it ever giving me problems before. Half-Life, at least in software mode, will sometimes have this "skipping" behavior when playing voice lines, but I'm guessing that's due to the performance issues rather than …

Working on a early 2000s retro box as a christmas gift for my brother. I'll post pics in another thread but is a very mini PC, like 12x12x4 inches, kind of cool. Drawbacks, it only has 2 PCI slots, and is obviously low profile, so I grabbed a cheap fx5200 which isn't ideal but seems to do the trick …

Hi Everyone Just to follow up on this. I did end up buying a C2Q 9300 for like a dollar. However while waiting for it to arrive I found something else on ebay from a corporate recycler - an HP G3 600 SFF for $25. Specs are pretty nice - i5 6500, 16 GB RAM, 256 NVME. Even has wifi/BT, USBC port and …

No, FastDoom doesn't use the FPU at all, so no difference between a 486SX and a 486DX. Just curious if it using the FPU would make it faster on systems with it present, assuming it is even possible? Doom uses trig lookup tables to avoid certain operations as they were too slow on most contemporary …

In case anyone was wondering - the solution was replacing the caps. I’ve just got around to ordering some replacement caps for the 3 largest ones on the card - a 470 uF + 10 uF electrolytic and a 470uF tantalum cap. After replacing them, the issue was completely gone - the card is now artifact-free …

IMO here's how I'd take it on an analog board for each machine: 128k/512k/plus: Reflow all large solder joints, consider recapping, they're really starting to need it on some occasions. Not a must-do though. SE/SE30: You can pretty safely leave them alone as drosse1meyer said. They're probably the …

Unless you have a specific problem (video or psu voltage levels) then I would leave the analog board as is. Note they're also fairly prone to cracked solder joints. As mentioned above, the SE/30 and later all in ones have a lot of issues with surface mount caps on the logic boards, those machines …

Are you using a pass through or manually changing the VGA cable to the voodoo's VGA-out? Are the games running? For example, do you hear any game noise when you get the blank screen? Does your LCD support the resolution mode of 512x384? That is the lowest default mode voodoo will start with iirc

So it will certainly be much faster overall despite the lack of a fpu? I would figure since I have seen YouTube videos of the 475 responsiveness and how fast games play such as sim city 2000. it should be decently faster but like you said anything that can take advantage of FPU would have to rely …

I'm not an expert on mojo.exe but the output looks OK. Detects the FBI, TMU, memory and doesnt hang at any point. Have you tried the DOS tomb raider 3dfx ver? (This could point to a problem with your Windows 3dfx drivers and/or installation)
