One complete Nova 3/12 system


How great is this! A Nova 3/12 with “Blinkenlights” on its way in! Awhile back, a gentleman called me and asked if I wanted his Nova 3/12? I guess you know the answer. :-) His system was used for real-time data collection and evaluation and was purchased in 1979.

Nova 3/12 Minicomputer System

As you can see from the picture, it is a two-bay system with one 6045 Phoenix 5+5Mb disk drive (one 5 Mb fixed platter + one 5 Mb cartridge disk) and a paper tape reader in the CPU cabinet plus two Diablo 44 disk drives in the peripherals cabinet drive (one 5 Mb fixed platter + one 5 Mb cartridge disk per drive).

I have been told that the CPU has the Triple Option installed which consists of Hardware Multiply and Divide, Memory Parity Generator/Checker and Memory Management and Protection Unit (MMPU). The system comes with complete documentation, about 20 spare boards and 17 disk cartridges.

    Nice to see a Nova 3D alive.
    I still have some spare parts available for the memories – both core and SC memories.
    Possibly also some PSU part, but I’m not sure.

    Cheers,
    Hans

    WOW! I found your site searching for the first computer I rememer: It was a DG Nova 2/4 in the office of my fathers company. He studied mathematics in Frankfurt early 60ies, then worked for a (today unknown) french computer company called “Logabax” as assistant to the CEO. After they went bankrupt he founded his own business and developed software (accounting, billing, etc.)

    It must have been around 1979/1980, I was 5-6 yo an I remember the design of the Nova 2 an the Diablo-Drive very good (of course it looked more seroius than the Nova 3).

    I’d give a lot, only to have the front console of a Nova 2 today.

      I have a DG Desktop complete, along with a multitude of software manuals and many schematics. I also have boxes of circuit boards from Nova, & Eclipse systems. All the desktop software, and some USGS data. If anyone is interested, please email.

    Sorry, I have to correct myself: my father went from LogAbax LONG BEFORE they were acquired by Olivetti :) Sometime my (and my fathers) memories are corrupted…

    If you don’t mind, I’d like to make some more comment:

    It was a key-moment for me, playing “moon-lander” on a terminal of the Nova 2. My father also was 30 over years a teacher at an adult education center in Offenbach near Frankfurt. I’ve grown up with “BIG” (relative to today) computers. Much I know today (i.e. how to use a soldering iron) I’ve learned from him.
