DEC produced IMP interfaces for the -10/20. They typically were bundled into the T systems (e.g. 1090T), but could be bought separately. DEC provided drivers & utilities for TOPS-20, but not TOPS-10.
KL10 - AN10 - I/O bus interface to the IMP for 1080/1090/1091 AN20 - Same, for DECSYSTEM-20 (includes the DIB20 - the I/O bus adapter for the KL) KS10 - AN22 (Yet another KMC11 + line card device) This may have been a repackaged IMP11-B. Both models come in standard (30 ft) interfaces, or with a long line (2,000 ft) interface. I don't remember the detailsl, but the long line interface was probably differential. DEC came a bit late to the party, but -10s were a large part of the early arpanet. And for most people, DEC field service represented risk reduction from homebrew.
