The small 5 volt regulator, the big "can", near the game/MIDI connector is a 78M05CH

Brad says:

OPL YMF262-M Similar to the Yamaha TX-81 Z synthesizer. If you like FM synthesis, it rates about a 5 or a 6. Compared to a good Wave Table, about a 2.

There is a FET type OP-AMP, a TL072c, located right under the 4 pin CD connector. I'm guessing by it's position that it is the stereo line out amp. Could be an input buffer, looks like there may be a trace running to it from the J6. Hard to tell, it's a 3 layer board.

   The sound quality is pretty good, but not in the league with the Audiovation. I made some transfers from my 1/2" Pro Audio digital recorder, and a portable DAT recorder, of live source material via the line inputs.

I cleaned them up in CoolEdit and then burned a CD. Playback on my stereo sounded just like the original tape, except that there was slightly more noise. It wasn't gritty noise, more like white noise. I'll make an educated guess that the S/N ratio of the Reply is in the high 70s or low 80s.

The original tape has a S/N of ~88dB. The limiting factor there is the Mic preamps I used (Mackie SR32 VLZ mixer).

Driver Settings

>I have a MCA Reply Card CT-2501 in which I am looking to get the sound drivers for it so I can get it going in my 9595 or 9577. Has anyone out there got these drivers?

Peter steps up to the plate and delivers:
   That is the Vibra-16. Hardware settings should be IRQ 5, Low DMA=1, High DMA=5, I/O=220h, MPU=330h

It will work out of the box with OS/2 Warp (3 or 4) with minor modifications to the CONFIG.SYS. Install the SB 16 driver and alter the line in the CONFIG.SYS to read as follows:

DEVICE=C:\MMOS2\SB16D2.SYS /C:1 /D:1 /H:1 /I:5 /A:220 /B:16 /M:330 /T:6 /N:SBAUD1$ /P

This *assumes* that the High DMA is mapped to the Low DMA which seems wrong, but works perfectly well. Other setting (/H:5) causes a "machine gun" audio output.

It also works right out of the box with Win NT 4 (server and workstation): Once running Win NT 4.0 (Workstation in my case) you only need to open "Control Panel" - "Multimedia" - "Audio Devices" - "Add ..." and pick the "Creative Labs Soundblaster 1.X, Pro, 16" driver. Then set the values for I/O addresses, IRQ, Low DMA, High DMA to appropriate values and it works. Still have the card set to I/O 220, IRQ 5, DMA1 (8) and DMA5 (16) and I/O 330 for the Midi device. Same setting as for OS/2 and Win95. Still don't know if the card is *really* in full duplex mode.

The setup even survived a Service Pack 6a update with no problems (which is not always given ...) Main disadvantage here: the volume slides are very "inverse logarithmic" .... the most part of the volume changes appear in the lower 5% of the way - after 1/3rd of the way the result is merely noticeable.

Win 95: once you'd installed the drivers (which are internally marked as  "Beta") you simply run the Win95 drivers update from Creative Labs for the Soundblasters.

Works fine with software like WinAmp 2.09 and CoolEdit 2000. I'd tested it on my
souped-up 200MHz 9595A ... but will work (at lower data rates) on slower processors as well. WinAmp may have to be set to "half decoding" and "486" in preferences / decoder.

Dead easy. (After several failed attempts and a long thread in this NG ...)
