Pioneer CD-ROM with A2000HD

[adz]

Hi all, I had a spare Pioneer SCSI 40x CD-ROM lying around and I thought that it would be a great if I could get it working in my A2000HD. I installed it, set the SCSI ID to 1, hooked everything up, turned my system on, and nothing, the HD led just kept flashing on and off, unhooked the CD-ROM and it all worked fine again, BTW HD is set to ID 6 and I am using a A2091 controller. I then tried my external SCSI ZIP drive, set it to ID 5 and the same thing, the system just sat there doing nothing. Any advice or am I wasting my time. Thanks in advance.

I doubt you're wasting your time.
Have you checked the termination?
Try the CD drive, or the Zip drive alone without the HDD, tell us what happens.

It is terminated at the HDD, via a jumper, didn't think of trying the devices on their own, will do, thanks :-).

It should look something like this:

[Terminator] - [CD(1)] - [ZIP(5)] - [HD(6)] - [Controller(7)] - [Terminator]

I think, will double check everything tomorrow.

To adz:

The Boot hard drive on a Commodore A2091 SCSI Controller card should always be set to device # 0.  Also, what revision is the Western Digital controller chip, 03, 04, or 08?  I think that a 40X CD-ROM drive may be too modern for the classic A2091 card.  Try a slower drive, like a 4X to 16X.  Make sure to check for terminator resister packs plugged into or soldered onto the drives logic board.  Some CD-ROM drives have a jumper for disabling the termination.  Also, are the resister packs still soldered on the A2091 board, near the 50-pin SCSI connecter?  You have to remove them to get the rear port to work properly.     :-P

:lol:


I don't get your logic "DoomMaster", you think that a slow drive with slow SCSI card is somehow better than a decent speed CD drive with a decent speed SCSI controler.

Trust me. I have an old GVP SCSI controler that is about 13 or 14 years old, it still works fine, and should work with some pretty fast CD drives out there.
I don't see anything wrong with our modern(ish) hardware.

@adz

try this:

HD=ID0

CD=ID5

ZIP=ID6 Terminated

Well, I got it working, the CD-ROM anyway, will worry about the ZIP drive later, now all I need is a file system and I am right to go. On another note, would I be able to boot from the ZIP drive if I got it going?? Thanks for everybody's help. :-)
