Good for you Tracy!   Now tell me, is this system in production or just a
hobby?

Subject: [HP3000-L] Converting A 7980S to a 7980A for a Classic

Having acquired 3 7980 tape drives, two of the A model and one of the S 
model, only the S model worked.

But I needed an A model to connect to my HP3000 Micro/XE.

The fix was easy, but figuring it out was a little more difficult.

This essentially means converting the S model from SCSI to HP-IB.

You can't just move the HP-IB card from the A to the S model.  The S 
model had only 3 cards in the internal card cage.  The older A models 
had 4.  The drive's display will neither show an HP-IB ADDR or SCSI ID 
display.

So I swapped the A model's 4 internal cards with the S models 3 internal 
cards and voila.  My Micro/XE recognized the HP-IB address and it was 
able to make it's first full backup in 2 years.

Now I can move off it's lone 7937 Eagle drive and RELOAD it onto some 
"newer" Buffalo chips I managed to acquire.  I think someone here was 
looking for that Eagle.
