The answer is that the emulation uses the address in slot 0 of the
address filter as the source address. The hardware doesn't care what
order the addresses go in as far as filtering is concerned; DECnet/E
puts broadcast in slot 0 and the physical address in slot 1, followed
by any multicast addresses.
Is the SIMH behavior also what a real LQA does? That would be an
interesting DECnet/E bug if so... Or does a real LQA just use the
physical address, as a UNA would?
Hi, Paul. Sorry for not responding sooner. Busy, as usual. However, I
did mark this for some later investigation. However, I now realize that
it's not trivial for me to test, as it would appear a RSTS/E system
would help. :-)
I honestly don't know how a real LQA do. Maybe John Wilson knows more,
since he have been digging into these kind of questions way more than
most people I know...
Or else if you have some realistic suggestion on how I would test this
on my machine, as I do have a 11/93 with a real LQA here (although an
LQA plus).
I can provide access to my RSTS/E machine with a DELQA if that would
be helpful.

Heh. C'mon. It's a GIGANTIC commercial platform. People who aren't
porting to OS X now will be porting to OS X later.
Better yet, though, would be to write the software in a portable
fashion in the first place, and avoid using OS X's hokey whiz-bang
"extensions" to UNIX. Then, very litte "porting" will be necessary,
whichever direction you're going. It's readily possible; I've been
doing it for years.

Thanks Brian.
I understand the focus on the commercial side first and then those efforts spinning off benefits to the personal/hobbyist side.
Just looked like there wasn't any more efforts focusing on Mac OS X, since its not a large commercial platform.
I'd appreciate if you could pass along the question if there are any continuing efforts for Mac OS X.

That is/was Camiel Vanderhoeven. He's working with Migration Specialties

him if he'd mind entertaining question from you about the ES40 project.
I'm running AlphaVM-Free from EmuVM on Linux. I suspect that one of the
reasons Artem has not ported it to OSX is that he doesn't have anything

Look at project's page at www.es40.org.
Sadly they stopped working on it before finishing.

Hello!
An ES40 project for OS/X? Where? And just for OS/X?

Apparently something was wrong with the configuration file for cde.
So I did a find / -name Xconfig
and that pointed me to /usr/dt/config/Xconfig, which in turn is a link to
/usr/var/dt/Xconfig.
The file contents told me not to modify that file, which probably happened.
So I copied it to /etc/dt/config, rebooted and all was well.
Why it went worng in the first place, no idea at all...

Well, have to test myself. It's so long a time since I've been working
with Tru64 that I've forgotten many details. It's late now so I have to
test tomorrow.

There is probably the last used desktop selection "xterm".
Try to select from the session options the CDE desktop before you log in.

The thing to do would be to see what happens if you load some multicast address (such as broadcast) into slot 0 of the 16-entry address match table, and the station address into slot 1. For a QNA, that's perfectly fine because all slots are equivalent and the device doesn't do any MOP. It may be that this was a later restriction that RSTS didn't obey. Or it may be a bad assumption in the real LQA that wasn't documented -- or maybe it's just a bad assumption in the SIMH emulation. I haven't yet looked for LQA manuals to give more clues.
Ah. I thought you had already checked documentation.
Well, I did now, and simh is right. Page 3-31 of the DELQA manual states that the first address is used as the source address for system ID messages.
So I guess RSTS/E just sets it up wrong.
