didn't these things need some sort of domain controller or something to boot? I remember playing around with one at the place where I used to work repairing old machines and it got a sensible display up but then refused to boot. Mind you, I seem to remember that it took two keyboards - a standard PC one and an HP-specific one... the whole lot went to the tip sadly, minus the SCSI disks which were formatted for a different system (mind you, I rescued a few good machines from that place over time - the Tower32/700, Tektronix XD88, Philips P3800, numerous Link 480Z's and BBC model B's to name but a few...) blowtorches work wonders surprisingly. It's very rare to toast a chip providing you're careful with heat distribution (not recommended for repair jobs on boards that you want to keep though ;*) cheers Jules
