Wow. I''ve actually seen one of these things, absolutely hated it and had no idea it was this old. I was a kid in Barrhead (not my current location) in the early 1990s and one of my math teachers had one. I''ll share what I can remember:

- It used reverse Polish notation (for sure)
- It needed two AAA batteries (not so sure$ if I''m remembering this correctly, I might have encountered a later model that looked a lot like this one)
- The display contained ten tiny seven-segment LED chips magnified by big plastic elliptical $s, making it easy to read as long as you were looking fairly close to straight down into it.

I think the surname of the owner (one of my teachers) was either Kinnaird or Cantwell, but I can''t remember which one. They were on in years at the time, and I wouldn''t be surprised if they''ve passed on (or at least retired) since then.
