I'll take a stab at that; I presume it's due to the naming convention for macro processors from Bell Labs. Consider m4, which itself was written as, "an extension of a macro processor called M3 which was written by D. M. Ritchie for the AP-3 minicomputer; M3 was in turn based on a macro processor implemented for [1]." (from, "The M4 Macro Processor" by Brian Kernighan and Dennis Ritchie, as distributed with 4.3BSD; reference [1] is to "Software Tools" by Kernighan and Plauger). Anyway, once you've got M3 and M4, you've got a naming convention; I'd think it a safe bet that there was an M5 that was an internal experiment, and that M6 was simply the next in line and was interesting enough to be documented in a tech report. - Dan C. Aside: the AP-3 minicomputer came up on this list a few years ago, when Dag Spicer of the Computer History Museum was looking for information about it. Near as folks could figure, it was the computer portion of a Bendix "stereoplotter" for creating terrain maps and the like (Adam Sampson figured that part out; others derived Bendix from part numbers taken from a US Air Force spare parts requisition document I found). > On 6/29/23 09:40, Clem Cole wrote: > > +1 =F0=9F=91=8D > =E1=90=A7 > > On Thu, Jun 29, 2023 at 3:37=E2=80=AFAM Noel Hunt w= rote: >> >> Many thanks. >> >> On Thu, 29 Jun 2023 at 17:14, wrote: >> > >> > Available at https://www.skeeve.com/bell-labs-cstrs.tar.gz >> > >> > Warren and Brantley and anyone else, feel free to retrieve. >> > >> > I have two sets - both are in the tarball so there are undoubtedly >> > duplications.
