We’d get the assignment for next class at the start, then he’d explain how to actually do it. I’d sit in the back and just /do/ it. Once followed the instructor out during his smoke break to point out an error in the assignment, which he corrected when we resumed.
He was my favorite college instructor. Good guy.
That was my first palmtop. Followed by a Poqet PC, then an HP 95LX. I don’t have either of those anymore, but I do have a 100LX I bought off eBay in the early Aughts and used for blogging.
