       | Thanks for the link. I still have two old hp9000s.

       | expectations for what computing should be at an early age.

         | I learned BASIC on an HP3000 circa 1975 or so.

           | DECWriters and a Hazeltine terminal connected to an HP2000
           | somewhere). Kids played HP BASIC Star Trek:

           | I remember my first program was a slot machine- so I learned
           | about generating random integers within a desired range.

           | teletype with a paper tape punch that communicated over a
           | modem to a local community college. Definitely not the norm
           | at the time for a high school.

       | We had an HP-150 in 1983, it felt like the future. 3.5" floppy,
       | touch screen. Incredible.

       | Unfortunately it was a loaner from HP and Dad had to give it back
       | eventually.

         | Aside from the fact that this presenter and presentation is
         | almost a stereotype of mac vs pc, it is interesting to see how
         | touch was used. There are elements that now look very familiar
         | -- PAM being much like the Home Screen of smart phones,
         | selecting text, direct manipulation of individual elements...
         | but of course it would have been a not super great touch
         | experience in both technical capacity to recognize the touch,
         | inability to drag (?), and most importantly, gravity working
         | against you here. The mouse would soon replace their vision for
         | touch and fix all these fundamental problems. Still cool to see
         | what they thought was important then: business.

       | I own a number of prices of vintage/retro HP hardware including
       | stuff that was from specific divisions (Agilent, IDACOM). I ended
       | up having a number of questions on these things and I'm also in
       | need of missing software. I wonder if these sort of things are on
       | topic here, even though information on them outside the
       | documentation I currently have is a log shot either way.

         | Caused me to search for "IDACOM". The PT500 protocol tester is
         | pretty neat. A color screen luggable with seven separate MC68k
         | processors, all running FORTH. And pretty cheap ($120+shipping)
         | for a used one. https://www.ebay.com/itm/HP-Idacom-

         | Looks like a MVME bus system.

           | 
           | Got a really good deal on one with the original carrying case
           | manuals and a lot of the software although I'm missing a few
           | disks that I want in particular. It also has a CGA video out
           | I'm trying to get converted to something like VGA.
           | 
           | There's a company that exists supposedly full of former
           | engineers for the company providing support. Or at least I
           | should say a website for a company. I tried reaching out to
           | them to get some information on the missing software but
           | unfortunately didn't hear back. I wouldn't be shocked if it's
           | abandoned but I would have imagined their domain / hosting
           | expired in that case.
           | 
           | I also made some minor progress on reverse engineering the
           | file system used on the floppy disks but haven't done much in
           | a while.
