There are some cases where extending the OS to understand new things is
useful. E.g. TCP/IP for TOPS-10, or the card punch I devised for the KS
that never existed in hardware, but allows GALAXY to punch cards as it
would on a KA/KI/KL.
What's the copyright on the various TCP/IP stacks for TOPS-10? I believe
the LLNL one is public domain?
I am unsure as to the rights on the KTH one, one I cannot say exists is
under a very restrictive license, CompuServe's SEEMS KTH-derived but I
lack source ... or distribution rights. I think the Stacken one also
differs slightly from a KTH one as well?
For TOPS-10, I still haven't recovered the earliest preserved sources -
which is what one would want to start a repository with. The media is
with CHM, but at last check, hasn't been read in. Once it is, I have to
do some sorting before it's published. My concept has been to start a
github repository for each OS with branches for each released
version. I have signed-out https://github.com/DEC36 for this
purpose. I have some unpublished MCOs for TOPS-10 that will help.
Similarly for TOPS-20, though that takes even more effort in the SimH
context due to the fate of KS support and the way the system fileystems
were laid out.
Do any of the MCOs cover the RP07 ONCE bugs in TSU04?
There are quite a few Y2K divots to tackle. One tricky issue is DAP, as
that's cross-OS. (And now there's VMSSOFTWARE (the company) to
consider.) In general, some thought needs to be given to what
categories of change are acceptable, and where. The main thrust of the
simulator effort has been preserving history. So there may be different
branches for "last DEC release + bug fixes", "last DEC release +
completing unfinished or internal use but never released work" (e.g. my
unfinished KS10 ethernet driver), and "new features/extensions".
I'd make it a "user's choice" type thing - I would for personal use eant a
rather extended version of the OSes, but for a project on the real
hardware I'd want "last + bugfixes".
The simulator community uses TOPS-10/20 under the terms of the hobbyist
license that Dick Greeley & I arranged while DEC was still in
existence. A user-driven project could not expand the terms of that
license, nor do I think it wise to draw HP's attention to it. However,
distributing patches/improvements for use under the existing license
would seem OK to me. I would want to be careful about any user
copyright/license text in such additions to be sure that they don't
appear to conflict with the DEC license. (I'm not a lawyer and do not
represent HP.)
As an interim solution, I have created
https://github.com/dec36.patches. If people care to provide their
patches (clone the repo and submit pull requests), it can serve as a
distribution point until I get to a more complete solution. I probably
won't do much review.
Do you have any dynamic disk geometry patches?
If Stacken gives the OK I would advocate for the addition of the command
history patches. ;)
At this point, I think FILCOM (/O) or SOUP/SOUPR against unmodified DEC
sources are the best formats. That way I don't have to deal with
setting up the full repo structure.
I'm thinking that's the best plan as well.
As for other OSs - I'm not taking those on...
Only Rich can speak for WAITS I think. ;)
