I DID get the CD-ROM Drive to work with the SCSI card that I have. It
happens to be a Media Vision ProAudio Specturm card, however you will
need the latest version of driver. In summary it sounds like it WILL
work on most systems, however you will need to get a driver from your
SCSI Card Manufacturer....

                                        Thanks for all the info!

The respones I received were:

#1- 150K/sec. sony/sun have new drives doing 300K/sec now out.

#2- dunno. all i know about sun cdrom drives is they do 150K / sec and that
sun put some stuff on them that makes it possible to boot cds orf them that an ordinary
drive doesnt let you do.

I tried this once when we got a new Gateway with a SCSI controller in
it. I was told by Ultrastor that I could do two things and it might
work :

1 - Clip the resistor pack of of the board at the external SCSI port
that they are using for a terminator.

2 - Get Corel-SCSI that might have a driver for it.

I never got a chance to pursue it. I am interested in what you find.
Especially if you find a free driver for it.

#1- Sorry, no info of that kind.

#2- I have the same drive connected to a 486 PC that I assembled, and it works
just fine. The only trouble I had was that the original scsi drivers I had
did not recongize the cd-rom. I downloaded new ones from the scsi card
vendor's BBS and everything works fine.

I don't have a lot of experience with cd-roms on pcs, so I can't really
guess as to the speed. If plays videos with sync sound just fine however.

Just did this on a PC here. No problems at all. Using an NEC sound/SCSI
card with a SCSI-2 ( new SCSI ) adapter cable. I am using the Microsoft
cdrom extenstion driver ( MSCDEX ) and it all plays just fine. What I have
found on other CDROMs is as long as its 'true' SCSI you treat it like any other
SCSI peripheral. As for thruput and access time, I know that the latest CDROMs
that Sun is selling supposed to be a faster drive and I think Kodak Photo CD
compliant. I would guess the specs for Sony 8012's are around 300 KBS. They
aren't dogs like some drives I have seen.
