#NEC CDR74/adaptec 1542
I jumped into this thread kinda late and don't know if anything like this
has been discussed but …
I'm having _big_ problems getting my CDR-74 working with my 1542.
I'm using both OS/2 (AHA152X.ADD and CDROM.SYS drivers) and DOS
(ASPI4DOS.SYS and ASW410 CDROM kit from Adaptec) and essentially the
problem is the same in both environments. I just purchased both card
and drive and there's no other devices on the SCSI bus.
Problem: When I try to access the CDROM drive the busy light on the
drive goes on, the disk spins, and after about 1 minute I get
"CDR101-Drive not ready". The disk continues to spin several minutes
after this.
I've tried all the troubleshooting suggestions in the NEC manual and a
wide variety of jumper settings and switch settings on both the card
and drive all with essentially the same results. The software
drivers seem to load just fine and recognize that the drive is "NEC".
I'm beggining to think the problem is either a) bad drive or b) bad
cable. I had to purchase a cable with a 50pin SCSI connector at both
ends separately because the CDR-74 came with a cable that had the
50pin connector at only 1 end (the other end would not fit the
1542). Is there a difference in 50pin SCSI cables that I'm not aware
of?
Any help would be appreciated. My system: 486-33 ET4000 Local Bus
