One big syntax change that happened between Macro V52 and Macro V53, was that
support for "line starting with comma is a comment" was removed. The change
that removed this support, seems to be reversible, i.e. a later Macro version
could have this support added back in. I don't know when the change for
semantics of complex macros was changed. Most of my efforts with early Macro
sources, are related to compiling the PDP-6 monitor sources that are available,
and it's been a long time since I've messed with that.
Can't help with V47. But my notes on Macro versions from 50A onwards, including
where they are available in the archives:
50A(441) 1-Jul-1976 As a Non-DEC update on DECUS 10-301
to add a user pushdown stack
Patch between DEC and Non-DEC seems reversible.
53(1020) 27-Feb-1978 Has edit history from 50A through 53.
TOPS-20 release 3
53A(1152) 19-Jul-1979 TOPS-20 release 3A
53B(1242) 3-Aug-1983 TOPS-20 release 6.1
53B(1244) 28-Jan-1986 March 86 TOPS-10 CUSP tapes
53B(1244) 13-Nov-85 TOPS-20 KS UPD
53B(1247) 29-Aug-86 Sept 88 TOPS-10 CUSP tapes

Subject: [Simh] even older PDP-10 macro
For my particular PDP-10 archeology, I need an even older version of
Macro-10 than I can find in the various archive tapes. My recollection is that
I need version 47, which would have been current about 1975.
Either a binary or source would probably do. I hope someone has an image of a
system tape from that era that was thought to be not important because there
were newer tapes available).
(back story; Either macro 50+ had new bugs or Dec deliberately changed the
semantics of macros. In either case, a compile that had complicated macros no
longer worked on macro version 50+, and even in the day I had to use "r
old:macro" to compile.)
