Hi,My Father has just got a pacemaker today.
That's when I found out that the hospital use a "special" version of OS/2 in thier programming computer for the vitatron pacemaker.
Apparently they've placed it in some special memory (e.g. ROM based) as the GUI came up in about 3 secs, the time to show BIOS ROM message included!!!
I wish that my computer will start as fast as that the next time 
It was attached to a HP Color InkJet 2230 and printed curves and charts etc. for e.g. heartbeats, settings and reports.
I saw it over the sholder on the nurse/doctor that used it and first noticed the "waiting clock" when they reprogrammed parts of the pacemaker. I could also see it on the scrollbars and checkboxes and radiobuttons that looked exactly as in OS/2.
The scary part though was that they just switched the computer off when they were finished, without shutting down the system.

I can't see the OS/2 style on the animation though, but when I looked at their page and searched for OS/2, they mention OS/2 for "Current Job Opportunities".
