Of course, but what I wrote was that a kernel configured for amn 11/53
wouldn't run on an 11/23. It would have to be re-SYSGENed.
like that. But a box labeled 11/53 and having an
11/23 procssor in it
is
an 11/23, not an 11/53. It won't run RSX-11M
or Ultrix configured for
an
11/53, or various things.
An 11/23 would run RSX-11 just not the I&D kernal, same for Ultrix
depending on version. >I'm surprised you say it's common. I can

It was happening when the processors were NEW. Seems
it made a very
compact fairly fast system if the DEC box was not used. However early on
getting the bare CPU was difficult so people bout 11/53s, snatched the
cpu
and resold them with commonly available 11/23s (as Micropdp-11s)
Oh, I see. I suppose that makes sense. It doesn't seem to have been
common over here, though.
I'm
thinking of
11/03 -> 11/23, 11/23 -> 11/73, 11/73 -> 11/83, microVAX -> microVAX-II
upgrades).
Yep, like my 11T03 that has a BA11N and 11/73 cpu
