Jerome Fine replies:

If RT-11 is your fancy - or even if it is not, at least it
can be a start, download the distribution from:
http://www.classiccmp.org/PDP-11/RT-11/dists/

You will need to UnZip the distributions, of course.
Then just ATTACH the "filename" and BOOT.

I intend to make V5.03 Y2K compliant if anyone
is interested, probably even Y10K compliant as well.
I would appreciate some feedback in the case of
Y10K compliant since there are a few things that
need to be defined. It should be possible to make
the Y10K enhancements at the same time as the
Y2K bug fixes. But the DATE value in RT-11 is
insufficient to handle more than another few years,
certainly not hundreds, let alone thousands. A
whole word for the extra year bits is my choice.
For disk files, a whole word is available and
for tapes, at least a thousand years is VERY
easy - except cassette tapes. I would appreciate
some help in deciding.

I hear there are RSX-11 and RSTS/E distributions
available as well, but I am an RT-11 addict.

Did I answer your question. I would appreciate some
help in setting up a compile/link environment for use
under Windows 98 SE unless you and other fellows
can change V2.10 source files to again provide VT100
emulation as does V2.9-11. But I would prefer to
spend all of my time in enhancing RT-11 distributions.

Sincerely yours,

Jerome Fine
