Re: Unplugging the keyboard = kernel panic ?
And having just pulled the keyboard from a running Sun 4/50 down in the machineroom/mausoleum/morgue/museum, I can fairly confidently state that that still doesn't cause a kernel panic.
Surely it'd depend on the OS, though?
Memory and Wikipedia both claim the 4c architecture ran SunOS (BSD-based) and Solaris 2 et seq. (SysV plus chunks savagely ripped from BSD). Or you could run stock BSD on it. And apparently there are Linux distributions, though I doubt a bank would have been using that in '96.
And then there's the question of OS version. And could the 4c's firmware be updated? (I haven't had one of my own since, oh, 2002, maybe. So I've forgotten many of the details. I did like those pizzaboxes as personal workstations, though, back in the day.)
