Does anyone have a DMC11 integral modem line card schematics set? I'm looking specifically for the part right next to the connector, i.e., the coax driver and coax receiver parts. I don't see it on Bitsavers.
That does have a line unit maintenance manual which has a schematic of the digital parts (in other words, everything up to the point I actually need the most) but it omits the analog part, saying to find it on "print D16".
The DMR11 print set does show a circuit for this, but it's very different from what the DMC manual describes and it has some aspects that don't make much sense, like a "sine generator" in the output stage.
