that tabbed package often has a pin spacing compatible with common 'through-hole' CR2032 holders so swapping it out with something replaceable might be easy. Well, thats exactly what I did. The CR2032 holder I had didn't have pin spacing that was compatible, but I salvaged one from a dead LGA775 …

The VBE aren't in ROM usually? That seems odd to me. A driver based solution sounds like a real kludge. It is kind of a kludge... most stock S3 Trio 64 support VBE 1.2 in ROM, which is all well and good (no "driver" needed fot VBE 1.2) but for games that need/want VBE 2.0 (e.g. Quake) then a shim " …

The game port specification allows for up to four buttons and up to four analog axis; it sounds like the joystick you describe with four buttons, two axis and a throttle probably falls into this "three axis" type of setup (with the throttle being a third analog axis). The reason newer digital …

I recently bought a Compaq Deskpro 4/33 motherboard, which I was all too happy to find. The seller reported it as working and, indeed, it turns on and reports "102 - System Board Error"... yay. :angry: Research shows this error almost always means bad CMOS battery and, indeed, the multimeter says it …

Yeah, there are many implementations of "AC'97" sound interface, and drivers for DOS would totally depend on the chip/manufacturer. For example, I have a machine with a VIA "Vinyl" AC'97 sound chip, and VIA provides DOS drivers for this one. You would have to check for drivers for your specific …

Honestly, I am not sure I should even be suggesting this but, electrically, it would be permissible to simply make a plain old basic splitter cable. All MIDI 1.0 spec devices should have their inputs all electrically isolated so this should be okay, my biggest concern is that the output is able to …
