200	Hi, Power supplies are OK and both drives are doing the same thing. I have tried it in the single drive mode and same problem. The only thing I have found is...	bob777_32119	Dec 10, 2009 7:31 pm
199	Hi, Did you check the disk signals and addressing ? Did you try to run the unit with one drive attached ? If it works then one of your drives is bad, if it's...	Rik Bos hpcalc	Dec 10, 2009 3:25 pm
198	Has anyone had any experience with repairing the 9122D other than the sticking drive problem ?? I have one that passes the power up self tests but the drive...	bob777_32119	Dec 10, 2009 3:14 pm
197	Hi John if that is a gpib program for control I am guessing one of two "equipment" people on the hp-agilent group might be interested in that image as well. ...	Alan Melia g3nyk	Nov 7, 2009 6:18 pm
196	Hi, I bought a 89050A module a few months ago. I was delighted to find that inside the case it is a 82929A Programmable ROM Module fitted with one EPROM. I've...	john_vc2004	Nov 7, 2009 1:24 am

194	Hi Everett, don't tempt me !!! one of the crazy ideas I put on my list some time ago was like what if I take out the complete CPU board and replace it by...	j_amodio	Oct 15, 2009 2:29 pm
193	Hi Steve, let me combine the response to your last two messages. There are two different "ROM drawers" for the HP Series 80, the most common and perhaps more...	j_amodio	Oct 15, 2009 2:04 pm
192	Hi again Jorge, You have confirmed my findings on this. Now, if the ROM Drawer has no logic on the board, is the EPROM Drawer similar or does it have a lot of ...	Steve Rooke sar10538	Oct 15, 2009 8:06 am
191	Hi Jorge, That sounds very interesting and it sounds like a good way to impliment this. In my case there is no need for the HP-IB interface as it's already ...	Steve Rooke sar10538	Oct 15, 2009 8:03 am
190	As I understand it with a bit of googling around, these are not just simple EPROMs and so that does not look like a way of adding ROMS to the ROM Drawer. Steve...	Steve Rooke sar10538	Oct 15, 2009 7:54 am
