While we're on the HP 2000 subject: Drug home two more HP1000s (first cousin to the 2000) last wekend. Both systems were mounted in racks and seemed to be fairly complete. The first system was a HP3095 test system. The 3095 series are used in conjunction with a bed-of-nails for the automated testing of boards and assemblys. The system included a HP7914 HD/TAPE combo, 768K of RAM, multiple HPIB interfaces, 8 port TTY card, I/O expansion chassis, misc other I/O cards (unknown). I was hoping that the RTE system was still installed on the disk but, looks like it won't be recoverable. The disk sounded like a coffee grinder when I applied power... Bummer :-( For some reason, the CPU was missing the ROM. I managed to steal the ROM The second system was a vibration analyzer. It included a basic computer, D/A and A/D interfaces, a 8" floppy drive, X/Y display, and system controller. There were no disks with this drive either which leaves me without an OS. If anyone knows where to find DOCs for a "HP5478C system interface" or "HP5477C system controller", I'd appreciate the info. From what I can tell, the system interface is a multiple channel DAC and the controller provides some external switching capability. I'd really like to know more about these. That box has a bad power supply. There's a red indicator on the front of the PS that just stays lit when power is applied. I think this is a fault indicator. There are no voltages on the backplane of that box. I stole the ROM from this box to get the other one going. I know where there is a 1000 crate that's mostly stripped. The panel, and all the cards have been removed but, the PS may be intact. If so, I should be able to liberate the PS. ID labels over the markings so, I can't even tell what kind of devices they are. Has anyone had experience dupping the ROMs from a 1000? I have tried to download the HP BASIC tapes from Jeff's site but cannot get them to work. The format doesn't look quite right and they fail the checksum test. Has anyone had any luck downloading those tapes and installing on a 1000? So... At this point, I have two working HP1000s, lots of I/O cards, a spare create for parts, and a bunch of other goodies. BTW: I know where there are some more systems. Probably go back this week and get more. See ya, SteveRob _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com
