Oh, I just realized that this _has_ been ported to modern machines. Perhaps ironically, it's part of plan9port, the port of (most of) plan9 to Unix: https://github.com/9fans/plan9port/tree/master/src/cmd/mpm A paper about it was in the Volume 2 of the 10th Ed manual; I was just looking to see if a PDF of that was floating around when I ran across this: https://archive.org/details/unixresearchsystemprogrammersmanualtenthedition… I'm not sure who this person is, but it seems like they've uploaded some cool stuff. https://archive.org/details/@yehudahamakabi Anyway, I didn't find a PDF of Vol2, but I did find this: https://github.com/Alhadis/Research-Unix-v10/tree/master/docs/vol2/pm (of course, the V10 source is available, but this is easy to grab). Running it through `groff -ms` gives output that's imperfect, but intelligible to get the main gist. Hmm, it doesn't seem to mention the post-processor at all; maybe that didn't come until later? Ken, Rob, do either of you remember? - Dan C.
