This is my latest project. I have an Emulex TC02 that I want to use with a
pertec formatted Qualstar tape drive, model 1260.
The TC02 is plugged into a Vax 4000/400, hobbyist openvms version 7.2. It
is curious but when I start the Vax it does not see the TC02, this is at
the console prompt stage, >>>> show dev does not list the tape controller,
but >>>> show qbus lists it as a tsv05. Is this correct?
Anyway when I boot the Vax VMS does list an MSA0: drive but it is not
online or available, just what does this mean?
I also have a Dilog DQ3153, but no cables to attach the drive.
Anyone have success with hooking a Qualstar to a Vax or PDP?

Sounds like it can see the controller, but not the tape drive.
Check the cabling between the controller and the drive (make sure the
cables arent upside down or something stupid like that), and make sure
the drive has power.

I always wanted to have a reel to reel tape drive and now I have one. The
mistake I made was not checking google before opening my mouth. I found
out that the TC02 does not work in Vax with VMS > 4.x, however I did put
the TC02 into a PDP11/53 and got it to work.
This was not easy since the only cables I have were about 18 inches long so
the tape drive had to be right next to the BA23 chassis and I only have
one!!!! tape and no write ring. So I used tape in place of a write ring
and got the PDP to actually see the tape and Init it under RT11 and read
and write to it. What a great feeling to see the tape move! Aren't old
computers fun!!!???
Any advice on cables? I need 50 pin card edge on the tape side and 50 pin
IDC on the TC02 side, the DQ3153 wants 50 pin male Centronics connectors
instead of IDC. What's a good place to order parts?

Frequently with a tapedrive offline means only that a switch need be
pushed on it's frontpanel, often depending on a tape load before it.
Trivial to us oldtimers, but maybe not to newcomers.
