Digital Equipment Corporation's 12-bit microcomputers and word processors include the PDP-8 (the first minicomputer, introduced in 1965), the PDP-12 laboratory computer, and the DECmate I, II, and III, WT-78, VT-78, and VT-278 word processors.

A Kermit program, Kermit-12, was written for these machines in PAL-8 assembly language in 1984-1992 by Jerry Sands, Randy Hippe, Martyn Hemmings, Sepp Stadelmann, Richard Schlerf, and Charles Lasner. It runs under OS/8, OS/78, OS/278, and OS/12. You can find the source code and documentation files at the Kermit FTP site in the following directory:

The files are the ones whose names start with "k12"; download them in text ("ascii") mode.
