V02C-02 is just one of the versions (out of about 23 versions) that are
available on the CD image at classiccmp which is available for download.
The V02C-02 version of RT-11 on the CD has 58 files with 1212 blocks,
although the date on all of the files is November 20th, 1975 or a week
earlier.
It would be interesting to compare all of the common files to see if
they are
identical. I suspect that they probably are.
What I am curious about are the two files:
ASEMBL.SAV
EXPAND.SAV
Did these two files do anything special?
For historical purposes, it would also be interesting to also preserve
the files:
BASIC.SAV
BAS8K.SAV
DEMO.BAS
that you have along with the F4.SAV (or FORTRA.SAV) which DEC
released in 1975 - probably V2 of FORTRAN IV. The early versions
of FORTRAN IV are available elsewhere for download
