[TUHS] long lived programs

Yep, sometimes that's the easier solution.    Remember the old Honeywell IMPs.     BBN wanted to move forward, but all the code was in 516 emulators (having been ported over from the PDP-1, they should have realized that portability would be important).   They built the C-30 to emulate the Honeywell.

Of course, this isn't even accounting for the VAX emulating the PDP and the like.

You do find some relics still running stuff.    I remember seing a new computer being installed at some FAA facilities.   It was some Apollo systems long after HP had pulled the plug on the DomainOS and the related hardware. 

I still remember a while when we were in the business of porting/selling MOTIF on a wide variety of platforms.    One day, the reps from Stellar insisted they need their loaner machine back.   This was a trade show unit and had an huge anvil shipping case.    I packed it up and put it on our loading dock.    The next day Stellar announced they were out of business.   I didn't think anything about it for a couple of years when I went out to our loading dock and said "Is this stupid thing still here."   They had never come for it.   I then was called into our sales manager's office.    Some guy needs a MOTIF for a Stellar.    I chuckle.    He goes "Yeah I know they're out of business."   I tell him that today's his lucky day.   I still have one.   I uncrated the thing, wrote him out a tape, and packed it back up.    Last I saw one of the CPU boards was hanging on the wall of our conference room as a decoration and another programmer and ripped out the Wyse PC the thing had in the top of it as a boot-up/maintenance processor to take home.
