Plenty of companies experimented with pocket and handheld computers in the early 1980s. Among them we must count HP, which introduced its HP-75C in 1982.

I peronally own an HP-75D (the successor model of this machine) that allows use of a bar code wand. I bought it on eBay around 2000, messed around with it a few times, and I think it’s been sitting in a box or a closet since. I couldn’t get into it, for some reason, like I could my TRS-80 Pocket Computer. Perhaps it’s time to revisit the 75D and try again — if it still works.

Still, I have a soft spot for the HP-75 series because it features similar industrial design as my beloved HP-11C calculator, which I’ve been using since middle school. RPN for the win!
