ISTR that Brad did a lot of work cleaning things up and
modernizing it. (?)

DEC-Alpha and Sun's SPARC chips were 64-bit since forever, and we
did ship official Solaris binaries once upon a time (did Paul
make those?).

I'd hazard a guess that there was a 64 bit [capable] release of
GRASS, used in production, 10 years if not more before the above
date of 2006. e.g. anyone know what hardware Lockheed-Martin were
running to run GRASS back then? I'm guessing it wasn't cheap 386s,
and anyway that predates the GRASS port to & rise of linux in

So my guess for the first 64 bit GRASS would be early 90s with
the emergence of the 64bit RISC chips. I never had a CRAY to
play with though, & don't know the history there. :)
