up late and working (classiccmp related)

Since the wife is out of town, it's a good night to stay up late and work on things classic computer related. I reached a milestone, so thought I'd share :) I now have two HP 7906 drives working flawlessly. 5 more to go. But instead of working on the others, right now I'm going through and running diags on each board in the 13037 controller... meaning of all the 7 or 8 13037 boxes I have, testing each card one at a time in a known working 13037. What fun. Very time consuming, but, when I go to work on the next drive, I can at least know any problems I run into are the drive rather than the controller. I'm also testing all the cards in the drive one at a time with cards from the other drives. Life is much better when you have two of an item to use as a testbed. I do have a 7905 as well... that one will probably wind up on the trading block - after I check it out and make sure it works. Anyone want a 7912? Heavy beast, and HPIB only so I have no interest in it. I think I'm going to go back and change my HP2000 Access system rack configuration. Move the paper tape reader and paper tape punch to the other side of the dual bay rack, and mount a 7906 in the spot where they were. Masochistic I tell ya. Well, this is all a milestone for ME at least, because I've always been somewhat "afraid" of working on 14" hard drives. But I think I'm getting the hang of it :) Well, diags just finished on the ECC board, time for the next card. Cheers Jay
