SB MCV (CT5320)

From Peter
Yes - from the principle. 
   However the card technically bases on the old 8-bit ISA (!!) card, roughly conversed to MCA and originally designed for Stage I and II MCA (80286 and low-end 80386 machines). They tend to cause bus timeout errors on faster machines ... and since you mentioned Win98 (which won't work properly on most PS/2) these will be your prefered machines I guess.
   Best recommendation: do yourself a favour, forget the SB MCV and buy a ChipChat or SoundPiper card. They have been designed and tested to work with the better PS/2.

>My nephew has a Soundblaster Pro running in a 76 Lacuna with DX2/66, Win95 fat16. Clean sound. Can't think of a solution, if timings is the problem.

Peter opines:
   I would guess that it is a problem with the relatively low DMA clock on the "older designs" PS/2s. The Lacuna supports synchro-stream and can run DMA at much higher rates for the individual DMA-request - the 9595-xMx is an old planar with a 10MHz DMA IIRC - which keeps the time-slices for the "lower" DMAs a bit short. The SB is known for holding its IRQ and DMA for extended cycles - which ends in bus timeouts (and error 107 or blue screens) or choppy sound. The "original Soundblaster" use the old 8-bit ISA designs, which are not just racers from the bus interface anyway. And -obviously- a bit off-MCA-standards in their circuit design.
   I had that with the Pro MCV2 as well ... until I decided to remove the card. The Reply Vibra suffers the same symptom - if you run them with the original SB-drivers. With the updated versions it runs much better.  Have one in my 9595-S20 "aol-gate" along with a Pentium-133 just now.
Nontheless the sound is a bit choppy when many tasks run at the same time -
particularly at Windows startup. Sounds odd.  So it is a basic design problem of the SB-compatible cards based on ISA technology. (As is the MCV2, Pro MCV/2 and the Reply Vibra-16 as well).
