Thanks.  I do think there is something bogus in it: the assertion that MPE V/R 
was a thing in 1983.  Yes, it was mentioned in an issue of Computer News, but 
(looking at that via the HP Computer Museum web site too, and thanks for that 
too) I think that was a statement about the future unbundling of DS/X.25 in MPE 
V/R.  Also that MPE V/R was a long time in coming.  We ran Q-delta-2 on a 
Series III for a long time while the Series 64 became a 68 and maybe a 70, but 
did upgrade it to MPE V/R when that came out.

MPE V/R was “MPE IV in MPE V drag”.  It had the MPE V name but its internals 
and system table structures were those of MPE IV.  (We had some home-grown code 
that looked in the JMAT for the next job number.)

The HP Computer Museum website now has a link to the version history file 
referenced below.

Happy to update it if there is more info or corrections.

Thanks.  Grabbed.  Those have most of the information I was missing being able 
to find easily online: dates and version IDs for classic-3000 MPE releases.  I 
wish I could still get the discussion text that led up to them because they 
don’t entirely fit with my memory.

The mid-1980s were kinda busy with MPE IV Q-MIT and its delta releases, which 
culminated in MPE V/R for the Series II/III and 30/33 (I ran it on a Series 
III), and MPE V/P which didn’t last very long, and then MPE V/E which had a 
future.  Sometimes I have trouble remembering what happened when.  I don’t 
remember more than one MPE V/R release (E.01.00) and it happened some time 
after MPE IV Q-Delta-2.

The tendency of links to go bad is momumental; the probability of it
happening over long time periods seems to asymtotically approach 1.0.

So everyone ought to make a habit of down-loading a copy of anything they
have an interest in; the existence of multiple copies seems to be the best
safeguard that material will not be lost.

I do pro-actively ask archive.org to save things that are useful, but I 
do also save some of them locally too. Usually I can find the 
archive.org copy before my own :-)
