Ah yes, now I remember everything: starting from some version I do not know (maybe just 7.04), DECnet binaries were bundled with CUSP tapes, and sources with Monitor tapes (see 704.BWR in the latter). The BB-X116D-BB tape is there just because it contains the key files needed to decrypt DECnet patches. Anything else in that tape is only for front-end DECnet support (DDCMP etc.). Thank you! That helps a lot. Looks like I should be able to get this working tonight or tomorrow! It contains NML.EXE too, which anyway will be replaced when installing TSUs, but until you patch TOPS-10, you'll need NML.EXE from the above tape. Ah. G. :)
