I have a DEC 3000 Model 600 and it has only one SCSI controller card in it. It has two blank slots for more SCSI controller cards. What is the type/model SCSI controller card(s) that I need?

Hi,

A quick Google threw up this site:

http://www.phys.ufl.edu/~prescott/linux/alpha/dec3000-sysinfo.html#600

The PostScript document there, suggests that you probably want either:

PMAZC-AA Dual Fast SCSI-2 Option Card
or
KZTSA-AA Fast Wide Differential SCSI-2 Option Card.

Good luck...

Regards,

Rob

Hi,

It depends on the type of SCSI devices you're connecting to. Most modern devices would be Single Ended (LVD) for which you'd need the PMAZC-AA.

However as this machine is getting on for 14 years old, I wouldn't like to guess as to what you're going to connect to it !!

The owner's guide here:

might also be of use.

Cheers,

Rob

Rob,

Thank You

I plan on putting more old devices. 8mm tape drives and SCSI hard drives. So do you think that I would be better off getting a PMAZC-AA

Hi,

More than likely yes...
