Try using the monitor's OSD to see what resolution it is detecting. That should tell you whether it is the monitor or the video card that is rescaling. My bet is that the 780ti is doing the rescaling from 640x480 to the monitor's native resolution and that's why the aspect ratio is incorrect. …

Would all together reach 18A? On the 12V rail? I doubt it would even reach one third of that.

nearly no Socket 7 Chipsets that have a 2/5 PCI divider. Actually, nothing aside from Aladdin IV seems to have a divider for Socket 7 PCChips M537 (the one with VIA VP) can set the PCI to 33MHz when using 75/83MHz bus. CPU is an mII-PR266GP (2x75MHz) Surely it's a 2.5x multiplier? 37MHz PCI is …

I know very little about Apple stuff in general, and I received an 800MHz iMac with a busted screen. Small areas of the screen are still visible so I can tell that it boots up, but when I plug in an SVGA monitor using an adaptor for the proprietary Apple VGA port there is no signal. I was wondering …

there is an alternate driver called cfadisk that you can install which should make the device detect as non-removable I'm not sure if it actually works in Win2000 though, the description only says XP. Before trying it, you should have a plan to revert the change if it doesn't work and causes a no- …

Decided to revisit my attempt at mixing ADPCM on the X68000. I hadn't noticed before that the description on page 303 of Inside X68000 is copypasta from a YM2608 datasheet and is NOT the actual format used by the MSM6258. It says on the previous page that the real format is 不明 (not clear) LOL. The …

On the ISA slot BALE is supposed to signal when the address becomes valid. On the IDE port it seems redundant since every I/O cycle will involve an IOR or IOW command and the address is certain to be valid already when that happens anyway. But if you are testing with a scope it looks like BALE …

This might sound funny but a while ago I was playing Hyper Dimension Neptunia rebirth 3 on Windows 2000, only to give up because it was crashing every time when Plutia first transforms.

PSU is probably fine unless you have several harddisks in there or something. The real question is what you are running on a P3 for which a Radeon 9600 isn't good enough. But if you can find a GeForce 7600 AGP that would be much faster in theory (totally limited by the CPU most likely) and doesn't …

Interesting. The unstated part of this is that after copying a few Windows files (win9x? win95 only?) to the 32bd directory, you then can go in there and run "WIN" but because krnl386 has been replaced by command.com it dumps you at a V86 mode command prompt without fully booting.

If the board doesn't have 2.5x and 3.0x multiplier settings, you can always mod the CPU to get them. Other than that, a Pentium 200 should work the same as a Pentium 133.

My Chuntex VL700 monitor was made in 1997. It is specced for 69KHz hsync, which includes 1024x768x85Hz or 1280x1024x60Hz. I was able to push it to 1280x960x70Hz with nVidia drivers. 1152x864 was good too. This is on a screen with 16" viewable area.

I would expect CGA to be fine but EGA has problems if the write combining buffer isn't flushed before different planes are selected via I/O port.

Does anyone know of a Windows program that can be used to set the user-defined instruments in an old Yamaha DX synthesizer? The DX100 manual says that it's possible to do this through midi. If there is no program around then I may have to write one... because entering the values on the keypad takes …
