We now know that anyone left on this thread is a solid, super-duper, senior.
We have a winner! I started programming in 1967 at the Camp Pendleton PX on an IBM 360-20 using RPG and a big stack of cards for a compiler. We eventually got some 7-meg disk drives that used removeable disks the size of pizza pans and throught we could rule the world.
We shifted over to 8-inch floppys in the keypunch section which obsoleted our cases of 80-column cards overnight - we ended up giving them to the military guys.
I see where some USB flash drives are up to 64 gig and that leads me to wonder if people won't be carrying personal data in their pockets and leaving nothing on the hard drives. That's gonna play Hell with the authorities when they seize some guy's computer and when they boot up, see Nelson saying "Ha Ha!"
