This is a double throwback, since I’ve apparently had this tab open for over a year, but feast your eyes on this sales training video for Radio Shack’s TRS-80 Model 100, a sort of proto-laptop introduced in the early 1980s.

My pal Rob actually had one of these in high school, which was astounding (later, Rob had the first Mac I ever saw, purchased the summer before he left for Rice). For the era, it was really amazingly capable — and as such, found a quick market with anyone who needed to write on the go, such as journalists. Remember, at the time, the alternative was to phone in copy.
