Well, I finally got around to ripping apart the HP3000 rack I got from John Lawson a couple of months ago. And desperately need some pointers... I've read the HP3000-L FAQ and searched most of the day for info, but there isn't much geared toward the Classic HP3000 home-hobbyist. What I've got is this: 9144 tape drive - I've already deduced that it's a low-density, 16-track capable of 67/134 megs and the tapes have to be purchased pre-formatted. 2563A Printer - with a modular connector. 9123 3 1/2" dual floppy - picked up after-the-fact at a yard sale. It's HP-IB, but has a weird DIN power connector cord. No P/S. (2) 7914 drives - one of these may be a non-op, having suffered some damage during transit. (2)HP3000 series 37's - these are piggy-backed, is this the usual configuration? . Here's where I need some info: The "top" unit has a DB-25F in slot one, and an HP-IB in slot 4, as well as those DE-3F (correct terminology?) connectors in ports 0-5. The "bottom" unit has the DB-25F in slot one, the HP-IB in slot 4, and an AUI (ethernet? Is this a Lanic board?) in slot 5, as well as the 3-pin deals in ports 0-5. Above the ports is a female Centronics-50 which connected to what I believe is a terminal splitter, p/n 40290-60003. Above that is a *very* high-density 99-pin male connector, this is attached to the board with the HP-IB connector. The two units are connected vi an HP-IB cable on port 4 of each. Also, the top has the keyed power switch for both. What I need is *really* basic info on the system and some pointers to information sources. Some quick ones: 1) How in the heck do the two 3000/37 units come apart? 2) How do I wire a terminal to this? 3) Is the AUI connector an ethernet card? A lanic card? 4) Could someone please ID all the rest of the ports? 5) Is there a graphical display capability on this machine? As an add-on? 6) What kind of Pertec tape interface is available for this machine? 7) If my 2nd drive is damaged, how might I go about getting an OS for it? I apologize for such a long post and my absolute lack of knowledge here. I had a buddy who was supposed to help me out (3000 guru) but he's just gone overseas for work indefinitely. It's such a cool system, the way it's put together, and there's a bunch of neat freeware that I'd love to use too. Any help at all would really be appreciated. Thanks, Aaron
