There are usually six 10mm diameter caps that are packed in too tight to up-size the diameter. = Four are 10x40mm 4700uF 10v. Their ESR is 0.038. You will not find those. They do not exist short of ordering them custom made. Best you can do is 3300uF 10mm with appropriate ESR. (Panasonic FK) Some …

Yeah, spoke too soon. Tried a different game and it crashed pretty quickly. It's completely frozen there, had to press reset.

Hmm, I'm not sure if the CT2600 has any way to disable the CDROM interface. At least I can't see any jumpers to disable it. Would putting the card into an 8 bit ISA slot help in that regard? I recall reading that the audio all runs through the 8 bit part, and the 16 bit part is only used for the …

Currently set to port 220 IRQ 7 DMA 1, but have also tried port 240, IRQ 5 and DMA 0 (the parallel port was disabled on the IO card). The current settings were what I previously used with success on the old motherboard. No other devices in the computer. I did have an AWE64 too for MPU-401 support, …

Bought a "broken" Gravis Ultrasound PnP Pro recently for $60 and just got around to testing it. It works perfectly. I had to disable the LPT port to get it to work as the Ultrasound seems to require both IRQ 5 and 7. Maybe that's why the seller couldn't get it to work. Oh well, no complaints here. I …

Are you saying the problems started happening immediately after you installed Windows 98? Or did you do something else in addition to using the install CD? I'm pretty sure I installed drivers on the Thinkpad (video, audio, etc), but these are all from IBM and the laptop does officially support 98. …

Okay, so it gets stranger. I've verified that the ISO I'm installing from is an original from MSDN (compared the SHA1 checksum). I've burnt it a couple of times just to make sure I didn't have a faulty CD. The problem happens even without me installing any drivers, so it's not a bad device driver …

Well, I've copied about 30GB of files to the Win2k installation and run Prime95 for several hours, and it seems okay... There might be some hidden corruption that hasn't caused the OS to crash though. All I can say is that it's still running and appears normal. Not sure what to think right now. I …

I've installed Win2000 on it now just to see if the problem is isolated to 98, so I'll install Prime95 and leave it going for a while. The power supply is the original Toshiba one which has always worked up until now, so I assume it's still good. Last night I pulled the whole laptop apart just to …

Hi I'm running Dosbox 0.72 on OS X, with cycles set to max. For the most part, games work fine and run at full speed. However, occasionally certain parts in a game will run incredibly slow (~1fps). When this happens, my CPU usage drops to almost nothing. The bits that slow down are usually …
