Having recieved my Platform 3P and 40 tapes from the good guys at HP... I pulled out the functioning piece of my Micro/XE in my garage and fired them up. The Eagles fired up green, the Micro/XE blinked for awhile and gave me a "B" and the HP7974 did a self test too, and gave me an F50 error. (I assume the lights correspond to the fact that they are not connected to each other in any way. I'm also sure among my dozen or so HP terminals one is still working.) Next step is to connect the pieces and see if I can Install and Cold Load from the tapes. I don't happen to have a HP7974 manual. Anyone know of the proper method of verifying and setting it's HP-IB address? (Not only that, but what address should I pick?) I'll also need to peruse my MPE/V manual and figure out the magic that tells Sysdump the relation between DRT numbers and peripherals. I've done this before but the last time was 10 years ago. Helpful suggestions are desired. Tracy M. Johnson TRW Automotive Electronics
