Is the CT1330A a Sound Blaster Pro 1 or 2? Because I have a Creative Sound Blaster Pro 2 Windows 3.1 FM driver (not the usual Voyetra one). The other uploaded SB Pro drivers all use the Voetra one.
CT1330 is SB Pro 1.0
CT1350 is SB Pro 1.0, revision 1
CT1600, CT1610, CT1620, CT1680, CT1690, and CT2600 are SB Pro 2.0
only CT1600 was retailed AFAIK, which has the Panasonic CD-ROM interface.... the rest are proprietary or SCSI
keep in mind that Creative has a tendency of reusing PCBs for their variations, so you can never go by the number printed on the board... that is not what they officially designate that particular card as.... always go by the FCC ID white sticker if you can, it will have a more specific "CT" number on there
for example the original SB16 card was CT1730... there was also the ASP chip version, but the card was also commonly called "CT1730" as it is the same board except with the extra chip added... but really, it is called the CT1740 according to Creative's product list
