Wayne,

Thanks for mentioning my beloved HP1000. This box was the love of my life, computer-wise.  From a very early age, I was fascinated by the empowerment of pushing a switch and causing some physical event. Building process control systems with the HP1000 was naturally a real thrill for me.

HP did extend the HP1000 many decades past their original drop-dead date, even introducing the A990.  At first, they tried to foist some special unix-ish box on us as a replacement, but it just wouldn't respond to interrupt-driven events as well.

And, talk about a highly-configurable OS!  RTE/HP1000 has been used as embedded controllers for banking ATMs, full-on business systems, data acquisition and process control of about everything, keeping offshore oil rigs afloat, switching telephone equipment, testing custom space probe batteries......... (and on and on).

The HP1000 would tolerate humidity around 10% to 90%, temperature about 40F to over 100F. Didn't like fast temp swings, though.

There are still many HP1000s in use today. Even a few RTE-6 boxes, I believe. Gee, I miss her!

The Apollo family of computers was replaced by the HP-9000 Series 400 systems
(Motorola 68xxx CPUs) which ran various HP operating systems as well as the
old Apollo Domain operating system.  Domain was dropped along with the Series
400s when HP shifted it's technical computers to HP-UX and PA RISC CPUs such
as the Series 700 machines.

Related to the discussion of how HP treats some older operating systems is
their recent ending of the HP-1000 family and the RTE operating system.  It
made sense to me to port RTE to the PA-RISC architecture but that did NOT
happen.  Bye bye RTE.
