DCC built Nova 1200 clones (as well as PDP8 clones, the D-112). They
were near-exact copies, but 20% cheaper, and came in both regular and
jumbo versions, just like the Novas. DCC made a few improvements,
replacing the switching power supply with a quiet linear supply, and
using wide bat handle switches on the front panel instead of the
finger-cutting toggle switches on Novas.
But it was basically a ripoff, so DG naturally sued DCC over theft of
trade secrets, and mostly won. I think DG eventually bought DCC, does
anyone know for sure? I also just found mention of follow-on D-216,
D-316, and D-416 machines. Has anyone seen one of them?

I'm currently sprucing up my D-116 for VCF East. I actually like its
mechanical design, since with the cover off the entire surface of the
topmost pcb is available for probing, without using an extender card:

I may be a little biased since I was an expert witness for DCC in the
trial, which is how I came to have this D-116.
What manuals do you have? I'm missing the D-116 user's manual which
gives the assembler, debugger, etc, syntax. I'm also missing
schematics for the core memory, and am trying to repair one flakey 8K
board.
