The biggest issue I've found wrt conventional memory on both PC-DOS 7.1 and MS-DOS 7.x is that HIMEM.SYS is a pig with 64MB of RAM, taking about 30kB of conventional memory. For some reason 32MB is significantly less problematic.

The two physical connections use the same MIDI UART. I think it would be more straightforward to split the MIDI output signal.

I'm wondering about NOS OEM replacements. Which models of Dell or Compaq machine from that era had power supplies that: came with standard ATX connectors? were of quality design from the likes of Delta? As PCBONES stated, any new PSU with VRM based 5V rails is going to be way overblown, and I'm …

Don't see why not, but why wouldn't you use the external jacks for external gear? Have you got a specific idea in mind?

Any particular reason why you want to replace the Cirrus Logic sound card with an AWE64? I just thought it would have better compatibility with games. Both are equally compatible IMO. The E-mu 8000 synth does tilt the scale in favor of the AWE64 though. The CS4235 is not a very desirable chipset. …

In this thread: Lots of people who have never actually listened to decent tube gear. I'm not saying that tube gear is better, but if you believe it's outdated garbage then the honest fact is that you are ignorant. Find yourself a nice, little class-A tube-driven headphone ampilfier, listen to your …

PCI is active low, so the resistor will be pulling high, and the mosfet will pull low when the irq is triggered.

They generally see significant distortion when driven into clipping. Plus, 99% of the time, I want to hear the sound and not the amp. Finally, this is on a digital computer, right. If you want a warmer sound, just process it.

Solid state amps have been constructed to drive all loads a tube amp can, with the same or superior characteristics, usually cheaper and more reliably as well. The only thing they don't do better is stand up to atmospheric effects of a high altitude nuclear blast. Back in the day, Bob Carver would …

First, what is an IRQ? In a nutshell, a device on your computer called the interrupt controller listens to the appropriate pin on the card for the voltage level on that pin to be disturbed from normal. If it picks up a signal, it alerts the CPU. On PCI devices, the interrupt pin will naturally be at …
