Curious what exact model is your MV PAS16? The PAS Plus had Sony interface and one model of PAS16 iirc. The Sony driver is sony_pfm.sys but think it only supported Sony CDU-535, not sure if it supports the CDU-33A. The Sony driver is in this PAS driver package zip: http://files.mpoli.fi/unpacked/hardware/sound … s/pasutl20.zip/

Media Vision PAS16SL ( sound card )
Sony CDU-31A-02 ( CD Drive )

Do you know what drivers I need ?
What software package do I need ?
What entries in Autoexec.bat and Config.sys ?

I need this for DOS/Win 3.11

Because your sound is working OK, have you tried sony_pfm.sys ? It may or may not work depending on the exact MV card model number (not name). It is used like any other cdrom driver in config.sys similar to an IDE cdrom driver but must be loaded after the mv sound.sys driver. Mscdex must be loaded in auto bat using same /d:mvcd001 or same as what is in the config.sys. See attached zip for the driver and text file.

Well, There appear to be at least 3 CDROM drivers.

SLCD.SYS
TSLCD.SYS
SONY_PFM.SYS

Which do you think I should use ?
( TSLCD.SYS ) comes with the PAS16 install package.

I would try the SLCD.SYS first as it actually the driver listed in the archive support list for Sony CDU-33A .
The TSLCD.SYS is for SCSI only.
Here is the original DOS cdrom install disk: ftp://retronn.de/driver/Sony_CDU33A/disk1/DOS/
here is the readme.txt: ftp://retronn.de/driver/Sony_CDU33A/README.TXT

The config.sys line should be like : device=slcd.sys /B:340 /d:mscd001 /v /c
Or whatever the Setup comes up with. If it cannot find the CDROM try: device=slcd.sys /B:xxx /d:mscd001 /v /c where xxx is one of: 230, 240, 260, 280, 340. Do not try 220, 300 or 330 as that could conflict with the sound card ports. Yes you may have to manually set the PORT since the card probably does not have jumpers to set the cdrom port or does it ? They are not the same as the base sound cards port address and would be separate jumpers.

Some random info I could find digging around in the PAS SDK files:

1// Each product will some/all of of these features
2..
3#define bMVSCSI      0x0008 // 0000000000001000b  SCSI interface

5#define bMVSONY      0x0020 // 0000000000100000b  Sony 535 interface
6..
7// CDPC feature list
8#define PRODUCT_CDPC		bMV101+      \

10..
11#if PROAS100				// Media Vision Pro Audio Spectrum Orig
12#define HWREVISION	0x00		// the H/W revision #
13#endif
14#if PROAS200				// Media Vision Pro Audio Spectrum Plus
15#define HWREVISION	0x01		// the H/W revision #
16#endif
17#if PROAS300				// Media Vision Pro Audio Spectrum 16
18#define HWREVISION	0x01		// the H/W revision #
19#endif
20#if CDPC				// Media Vision CDPC
21#define HWREVISION	0x01		// the H/W revision #
22#endif

Unfortunately, while one of the header files does have some commentary on the relocatable address of the card, it does not provide offsets for the various interfaces on it. It seems that the Sony interface was used on a "CDPC" variant of the PAS16. Not sure if that's at all helpful.

Oh, and TSLCD.SYS is the Trantor SCSI CD driver. It won't help you here, AFAIK. In case this catches any Google hits, I had to use the Trantor SCSI Works package to get additional SCSI support to work for other SCSI devices, like a ZIP drive. The MVSOUND.SYS driver does not provide an ASPI interface, so the Adaptec ASPIDISK.SYS (etc.) will not load.

nice card, can you post some pictures?

that pack must have had come from one of those media vision fusion cd16 packs

here are some drivers for cdrom http://ftp.mpoli.fi/pub/hardware/CDROM/OTHER/

whats the difference between model cdu 33A and 31A ?

If my memory serves me right, the 33A is double speed and the 31A single speed 😀

With TopTek Golden Sound Card Pro Deluxe, depending on jumper J3, the soundcard would either be 220 and the cd 320, or the soundcard 240 and cd drive 340.

Thanks to this post and some more troubleshooting I finally have a working CDU33A 😀 Thanks All!
