DGC Nova 2: looking for parts & info, exchange possible

A belated thank you for the excellent photos; I completely lost track of this thread. As Tom already pointed out, all three of those "DGC NOVA2 16K MEMORY" boards are burnt/failed and will need to be carefully checked out and repaired before proceeding.

Tom: Do you have the schematics drawings for this board? I've never seen them and would certainly appreciate a copy.

You also have four Nova 2 CPUs; two are 107-000295 and the other two are the later 107-000431. I don't know what the differences might be between those two variants; one imagines that the 431 is better in some manner.

You have three BASIC I/O CONTROL boards, all populated with the same subsystems:
- 4007 BASIC IO CONTROL
- 4008 REAL-TIME CLOCK OPTION
- 4010 TELETYPE INTERFACE
- 4011 PAPER TAPE READER CONTROL
- 4011A LOW SPEED READER CONTROL
Two have been enhanced with daughterboards to allow for a greater range of interface speeds presumably for a serial connection to a terminal.

That leaves:

#2: DGC QUAD MULTIPLEXER <- appears to be just that, probably 20mA, with 10-deep buffers
#3: DISK PAK CONTROL DGC NOVA <- documentation online for 4046 / 4047 / 4049
#8: DGC NOVA IPB <- InterProcessor Bus thingie?
#10: DECON MX915 I/O Controller <- appears to be a TTY-style interface using GI UART
#16: ADC PLT LPT DGC NOVA <- appears to be three-purpose interface minimally populated

Have you decided what to do next and/or made any progress?

If you decide to sell I could certainly use a BASIC IO CONTROL board. Where are you located?
