Are you kidding on the old IBM? If not, THAT is hilarious.
Thats a mainframe console - it'* a terminal, nothing to do with a pc or dos, and you have to know commands like 'svts d g', '* psysjobs,j=gspp1$01', "$fprt3,120", and one of the more useful ones "k e,1"
The users see nice windows like screens but on the operations end we (everyone) still use green screen terminals.
Won't have a pic of what I drive til this weekend since it'* just a weekend job. It'* a big Ford F150, 250? Diesel Cargo van I use to set these things up.
The van has HUGE lettering on the side that says DINO JUMP and has our phone number. Really have to watch to be courteous to other drivers.
