Re: Roland SCC-1 - MIDI garbled?

I see on the card there is a NEC D6376 (AUDIO 2-CHANNEL 16-BIT D/A CONVERTER) and 2x 5218A (DUAL LOW-NOISE OPERATIONAL AMPLIFIERS - DUAL POWER SUPPLY TYPE) ICs. I am thinking of replacing them, first the D/A converter (since both channels are screwed) and then the 5218As ... I can't detect any …

Those are definitely speed sensitive games. Some of them received patches either for machine speed increases or specifically for sound drivers. The sound driver updates work because of certain sound cards but rather because of the faster machine speeds affecting the sound. I am certain it has …

SCSI is definitely easier to set up, and the controllers have less CPU overhead Speaking of - Is there a good piece of benchmarking software for observing I/O and CPU performance from one controller to another? A way to benchmark different I/O cards, basically. I may have an opportunity to compare …

Anywhere from 486 to Pentium 233 MMX is the DOS gaming era, basically the whole 90s. lol No. The DOS era stretches back a lot further than a 486 and the 90s. What's best depends on what you want it to do. This will always be the million dollar question. Be it "pure DOS" or simply "DOS" - it …

If I had to guess, you are going to have to pull off the front bezel to get to the screws securing both sides and possibly the top. After that, the top/left/right piece can be pulled off as one from the front.

What a wonderful restoration/clean up project, Brickpad! Whenever I see a full tower like that, I feel like it needs to be loaded down with filler for the 5.25" bays. Tape backup, 5.25 floppy, CD-ROM, etc..

I think a Voodoo2 wants at least a 300 MHz Pentium II CPU for most games On the contrary, by the time I hit a Pentium II 266, I was running dual Voodoo2s in SLI. P2 233 Mhz was the minimum requirement for SLI. P90 was actually the minimum processor for a P2 alone. That was also a beauty of the …

Even if you can't power up, can you just drop your volume to 0 prior to shutdown? I just powered up and shutdown with the speakers on (low volume, of course). The sound mine makes is not even half a second and sounds similar to what you describe in terms of pitch - like an Atari laser sound or …

Hey Ozzuneoj. I actually experienced that sound for the first time since installing a YMF719 to my system. I didn't really notice it previously because I run everything to a mixer and power down all audio stuff prior to shutting down the computer. I was on headphones and still had the mixer on when …

Man. That is tough to hear. It is possible that you have a mobo issue as jesolo originally mentioned. That might include a capacitor problem. It is also possible that your power supply itself is not up to snuff. A power-related issue can cause unpredictable problems, and adding the joystick (which …

If the games uses miles sound drivers: Rename SB16.DIG to SB16.OLD. Find SNDSYS.DIG from elsewhere and rename it SB16.DIG. Your milage may vary. It seems like that is the only option available. Unless they have an odd rename of the drivers, I think whatever sound logic EA used must have been …
