PDP-7

We have 8 warehouses stuffed with mainframes and minis. Around 120 of them in total. This belongs to the Norwegian Museum of Science and Technology, and with so many machines, there's BOUND to be a -10 there too :). On average, the museum recieves a query for pickup once a week. They also ran a mainframe on public display 15-20 years ago, but this was a Norwegian machine (NORD-1 i think, brilliant machine) and the people who knew about it didn't have the time it took to keep the mainframe going. This machine has been upgraded to run PDP-9 software, and has a switch on the front panel named "USE" with the options 7 and 9. It also had a homemade Automatic Priority Interrupt, nicknamed "Poor man's API". It has an oscilloscope display, two TU55 tape drives hooked up to a 550 tape controller, and the EAE (Extended Arithmetic Element). Picture at http://tore.nortia.no . Yes, we have a full set of schematics, except for one board (and with godly precision, this is the one we need), the Teletype Interface Card, seated inside the teletype. It is numbered 1818(twomoredigits). If I restore this -7, the Museum might let me inside one of their warehouses, and maybe restore a timesharing system, like, for instance, a -10. But, I'm going to keep focused on this task (for now ;) My dream has always been logging on a timesharing system with a VT terminal. IF the warehouse has a 15 in it, i'll ask them very nicely for a TC15. Who knows. We do have tons of -15 documentation (ask me not why) at the University, and even some -15 OS DECtapes. Thanks a bunch!! -Tore On Fri, 23 May 2003, Robert Garner wrote: ______________________ |Tore Sinding Bekkedal| |toresbe(a)ifi.uio.no | |+47 91 85 95 08 \_________________________ |"Sure, so life's a bitch.
