I'll post a message about that whole topic tomorrow. Quite a few people I
know working with this equipment have never heard of this message list nor
found the OS images on the internet. To go one step further, old DEC (now
compaq) told me outright "We thought you were a hoax. Who in the world would
want this old junk" - they were talking about PDP1,PDP-8,and PDP-11 hardware
and software.. talking about the left hand not knowing what the right hand
is doing.... :-)

Again, I take it these images are not "distribution sets". I a hoping to
post all the distribution sets of the various PDP-8/11 OS soon (sysgen
stuff). Really need that for old hardware. For years I needed drivers or
pieces of RT11 only to find numerous sites with "RT11 programs, DECUS ,
etc.." but not the real install media. I only ever got all this stuff from
purchasing large systems from factories.. Now it's easier.. I am getting it
all from the source.

I was actually told "can't". It would not run on QBUS stuff. Probably an
error, no idea.

One would hope....
