TK50-GA external SCSI tape unit + Microvax 3100 Desktop - test-drb@ccmp.vtda.org

2 Dec 2001

The problem may be that it's not a SCSI TK50 but the SASI
interfaced TK50 for the MV2000.  The difference is the firmware on
the SCSI/SASI interface card.

...
 Some more datapoints, please:

- Do you have a TK50 or a TK50Z (I think the "Z" is the indication that
it is indeed the real SCSI variant)? Does it have an SCSI-ID-switch on
the back?
- What model is your '3100? Just plain "MicroVAX3100", or is there some
M-Number (like "M40")?
- What *does*  "SHOW DEV" say?
- Do you have one or two SCSI-Busses? Or, maybe easier to answer: Does
the machine have a floppy drive installed?
- Does one (or both) of the internal disks "disappear" whenever you plug
in the TK50?

Anyway, usually problems with SCSI-Devices are due to either termination
problems, bad cables or conflicting SCSI-ID's.

regards

  Hello. I have one problem I'd like somebody
could 
 help me to solve. I have one TK50-GA external 
 SCSI tape unit + Microvax 3100 Desktop. 
 The Microvax can't detect the TK50. This tape unit 
 works perfectly. I have the cover of it retired, and 
 I have located the ribbon that aid to select the 
 SCSI address of the unit. The Microvax 
 haven't attached any other external unit, and 
 internally have two disks. 

 How can I know if the unit is attached ? 
 The SHOW DEVICES in the boot ROM don't says 
 nothing.
