Moving the Data General Nova 3/12 from Uppsala to my storage facility

Data General Nova 3/12
Today I took the commuter train from home to the city of Uppsala. At the Uppsala train station I was picked up by Karl-Magnus Pettersson who has a Nova 3/12 that has been sitting in his garage since 1995. In addition to the dual cabinet with the Nova 3/12 CPU that also has an expansion chassis, was Karl-Magnus documentation of his software written in Fortran 77, 17 (yes, seventeen!) 5 Mb Disc Cartridges, some spare boards and an extender board! Great! Although there is a way of moving the CPU board to the top slot and wire wrapping a couple of wires from slot one to slot 12 to be able to troubleshoot the CPU board, having an extender board makes troubleshooting any board a lot easier. And getting an extender board is like striking gold!
After loading the system onto the trailer we drove to my place where the Nova 3/12 now is in my storage room.
Thank you very much Karl-Magnus.
Picked up a Nova 3/12 from my friend Bjarni

A fellow Data General minicomputer collector offered me his Nova 3/12 a while back and today me and friend went to his place to pick up the Nova 3. Bjarni, as the friendly guy he is, also offered me to take his Model 4234, Diablo drive which I did. I now have a DG 19” rack, the Nova 3/12 CPU with:
- NOVA 3 CPU, PWRFAIL, PRLOAD, 256KW
- NOVA 3 TRIPPLE OPT, MMPU, PAR, MUL/DIV, RTC
- 64KW Plessey, 128K SC, W PAR, 0-127
- DGC NOVA CASSETTE I/O, $TTI/O, 9600 B, RTC
- DISK CARTRIDGE CONTROL DGC NOVA, DKP, 4234, 6030
- DGC NOVA CASSETTE I/O, $TTI/O, 9600 B, RTC
- A 4234 Diablo disk drive and a 6026 Vacuum Tape Transport
I believe the Diablo disk drive was part of the Nova 3/12 system since it has a disk controller installed for the Diablo drive.
