Since we're talking HP3000 war stories...here's one...
 
In a prior life, I was with a consulting company which worked with the US Navy.
The project was based at the now-defunct Phila Naval Shipyard and involved
the use of the HP3000 and a custom-made Powerhouse app.
 
To put this system into production, a Micro3000 had to be loaded onboard
an aircraft carrier for "sea trials" - which involved not only testing intermal
components of the ship, but the ship itself was put through some nasty
maneuvers - including one called a "crashback" where the ship was placed
into forward, full throttle, then placed into reverse - full throttle.  That ship
shook like a damned earthquake!  Other maneuvers included serpentine
steering which took the ship to a 40 degree angle...Remember that an
aircraft carrier is "football fields" large (and dosen't take this shock too
well).
 
Guess what stayed up and running through the whole thing?  Good 'ol
"Mighty Mouse" (the code-name for the Micro3000 before it became the
Micro3000).  I'd like to see any other system do that, not just the AS/400.
It took a lickin' and kept on tickin'  (sorry Timex :)
