3B2 progress

About a year ago I was given a 3B2 1000/70 by Josh Dersch that I've finally gotten UNIX booted on (in a fashon). I've been spoiled by modern variants of UNIX that include the disklabel program in the miniroot, and it seems that 3B2 System V doesn't. The FAQs seem to address either installing on a MFM drive (V3 (500+) 3B2s are SCSI based), or bringing up a drive in parallel with a valid install (the original drive died), or installing on an AT&T sourced drive that's already been labeled (not an option). (A) Does anybody have the "3B2 Computer Maintenance Utilities" or "IDtools" floppy image floating around, or is this the one that I have with filledt and dgmon on it? (B) is the SCSI-FMT tape the equivalent of IRIX's standalone fx for setting up completely blank disks? (the one I'm using is an ex-Sun Seagate). (C) backplane slots: my machine is an interesting hybrid: it's a 3B2-1000/80 backplane with a 3B2-1000/70 system board. I'm trying to figure out if I have Pbus (looks like these are just an extention of the system bus), B?Bus (some buffered permutation of the above?), or something else entirely, since this machine came to me with a PE card (multiprocessor board). How much of the wiring is backplane-dependant, and how much is system board dependant? Anyone have spare bits for one of these? I wouldn't mind a network card, or more I/O (serial or serial/parallel). One further warning: if you use a SCSI cable scavanged from a dead HP 9000 Nova class (or the HP 3000 equivalent), be forewarned that on the end that connects to the backplane the IDC connector is installed backwards (as opposed to the ends that connect to the disks). I blindly assumed that SCSI was SCSI and d idn't think to check until it didn't work. ************** Get trade secrets for amazing burgers. Watch "Cooking with Tyler Florence" on AOL Food.
