Re: QBasic games.

So everyone who had DOS 5.0 or later, had QBasic, and therefore gorilla.bas Earlier versions of DOS had GW-BASIC, …

in DOS
What you propose is more like "get the sound card emulation code from DOSBox and run it natively in DOS". That's also theoretically doable. It might be worth looking into SoftMPU: http://bjt42.github.io/softmpu/ SoftMPU basically took the Roland MPU-401 emulation from DOSBox and uses v86 mode under …

Tubes behave in a far more benign fashion when driven to the limit where transistors (especially BJTs) respond with clipping and extraneous high frequency harmonics. The distortion happens to be more useful for you guitar people. Of course, amplifier design can have a strong influence on the sound …

For guitarists at least, the beauty of tubes is that they distort. The more they distort, the better. It not only gives a particular sound, but it also gives a particular feel to the guitar. As tubes distort, they also compress the signal, which means the guitar effectively becomes more responsive …

TDP isn't really important, since you need to keep die size and transistor count in mind. It still get's very hot and heat must be dissipated. Otherwise, hot spots may emerge which can kill the CPU. 4.5W is like a tiny light bulb, like the ones you use in a bicycle. Really, it's no big deal, …

Technically any 486 CPU bellow 50Mhz. does not require a heatsink. But heat is a big enemy of electronics so it would be nice to have some cooling. You should see things in the proper perspective though... A 33 MHz 486 has a TDP of 4.5W: http://www.thinkwiki.org/wiki/Intel_486 4.5W isn't exactly …

Thanks for the explanation! :) So I assume it's not possible to write a software-based TSR that uses polling method to monitor a given i/o port and then sends a copy of that data to another location ? Not without patching the software. However, for the Tandy sound card we had a similar issue: …

Ill do it if someone zips up DXCapsViewer and sends it to me. I couldn't find the program when I went to do this last time. It used to be included with the DirectX SDK, these days it's integrated with the Windows SDK. I've zipped up the last DX SDK and the latest versions here (not sure if the …

Yes, if you have a regular case with a PSU with a fan, there should be enough airflow for a 486DX-33. These were some of the last CPUs to not require any heatsink or fan. I don't think there is a way to monitor CPU temperature with software. This requires a temperature sensor in the socket, which …
