US Patent 4,099,439 describes the Polycom chip.
I have the original service manual (both volumes, latest version 12/79) and
there is no Polycom block diagram in it.
The custom Polycom chip (DM7670) was fabricated by National Instruments for
Moog Music. When Bob Pease was still around, I asked him if NS still had
any info on this part. Bob asked around, but I never heard back.
Congrats on the new job, new town, and new home. I also went through the
same thing in 2021 (I'm ~1hr from Cape Canaveral Space Center). Relocation
is a big job!
