There are 3 distributions on TUHS that have the same general name and number of source files for the "typesetter c" compiler and the "new" troff in C: https://www.tuhs.org/Archive/Applications/Spencer_Tapes/unsw3.tar.gz ./usr/source/c_compiler ./usr/source/formatters/ https://www.tuhs.org/Archive/Distributions/USDL/spencer_pwb.tar.gz ./sys/c/c ./type/croff ./sys/source/s7/croff https://www.tuhs.org/Archive/Distributions/Other/Interdata/interdata_v6.tar.gz ./usr/source/c ./usr/source/troff The Spencer PWB tape appears to be 1.0. Dates on files from sccsid comments on nroff/troff and throughout the system are from early to mid-1977 making this the earliest set.[1] The files under the ./type/croff directory and ./sys/source/s7/croff are the same. The UNSW AUSAM tape has the same files as PWB. An initial check shows some feature flags and structs from PWB are missing for [nt]roff here. However, there are extra notes on the c changes and the October 1976 NROFF/TROFF manual source for content published in the PWB documentation. The latest dates on other files are from early to mid-1978.[2] The Interdata files have lots of added comments and changes with a late 1978 date listed in some files[3]. It does have extra READ_ME files confirming that this was pre-release v7 c compiler for v6, which helps validate the PWB and UNSW content. I'll work from the PWB and UNSW files with the plan to send troff details to the groff list and rebuild the compiler in the process. Glad to confirm if the build succeeds and I find out any further details about the compiler if relevant for TUHS. 1. Examples: ./usr/man/man0/introduction: May 1977 and ./usr/man/man0/documents: August 1977 2. As printed in the copy available at: http://www.bitsavers.org/pdf/att/unix/PWB_UNIX/Documents_for_the_PWB_UNIX_Time-Sharing_System_Edition_1.0_197710.pdf Updates like the January 1978 changes to the dz serial code provided by Dennis at ./usr/sys/dmr/dz.c. 3. Such as ./usr/doc/cman/cman1: June 1978. Best, Dan
