Folks:
Long story short, I have a unpublished manuscript that a faculty member in my department
wrote late 1980's early 2000's. He did the entire thing in troff, eqn, and
pic.
The faculty member is still alive. A publisher is interested in the manuscript. I have
all of the source files on an old unix machine that still has troff, eqn and pic. It also
has groff. This issue is that the pic commands are bracketed by .G1 and .G2 not .PS &
.PE. The original machine he would have used would have ran AT&T Sys V on an AT&T
3B20. Below is one of the files. Any thoughts on the .G1 .G2? I can get the files that
have only eqn and troff to create postscript, but the .G1/.G2 is not understood by pic. I
tried replacing the .G1/.G2 with .PS/PE and it failed. I must be missing another program
that uses the .G1/2
Thanks

There part of heirloom troff distribution and are likely to just work on a

Btw. The heirloom version of troff is from Solaris SVR4 which should be
quite close the version from the 3B20

groff(1) says:
A free implementation of the grap preprocessor, written by Ted
Faber ⟨faber(a)lunabase.xn--org-e76a, can be found at the grap website
⟨http://www.lunabase.org/~faber/Vault/software/grap/⟩. groff
supports only this grap.
Distributors often have a package of Faber's grap. I'm not aware of any
other in circulation. (Happy to be corrected here.)
Please contact the groff list, groff at gnu dot org, if you have any
problems using it to format these documents and/or to note formatting
discrepancies between Unix troff and groff. There will likely be some.
I've noted differences between DWB troff and Heirloom troff, so using
the latter does not guarantee identical rendering, and moreover
DWB/System V troff has some bugs/limitations that Heirloom and/or GNU
troffs have fixed, and some of these can affect formatting.
Here's a list from groff's tbl(1) man page, for example.
GNU tbl enhancements
In addition to extensions noted above, GNU tbl removes constraints
endured by users of AT&T tbl.
• Region options can be specified in any lettercase.
• There is no limit on the number of columns in a table,
regardless of their classification, nor any limit on the number
of text blocks.
• All table rows are considered when deciding column widths, not
just those occurring in the first 200 input lines of a region.
Similarly, table continuation (.T&) tokens are recognized
outside a region’s first 200 input lines.
• Numeric and alphabetic entries may appear in the same column.
• Numeric and alphabetic entries may span horizontally.
One can imagine how a 200+-row table could format differently between
DWB/System V and GNU tbl, without either being "wrong".

Branden

This isn’t helpful, but the .G1 .G2 look a lot like Gerber codes used in NC machine tools.
