Reply SB16 (both versions use same PCB)
Driver Settings for NT, W95, OS/2
Thanks to Peter, we are back up!
ADD For Vibra Chip, VIBR16D2.SYS OS/2 2.1, 2.11 &
Warp Mar 1995
The small 5 volt regulator, the big "can", near the game/MIDI connector is a 78M05CH
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.
Pin 1 Common
>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:
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.
Works fine with software like WinAmp 2.09
and CoolEdit 2000. I'd tested it on my
Dead easy. (After several failed attempts and a long
thread in this NG ...)
