Mark Carroll's Journal

I remember my first calculator, back in the early '70s, a four-banger with a nixie tube that I got in a 'selling stuff for the school' thing. I thought it was amazing. I later had a TI scientific that had the magnetic card reader, sold it to a friend whose dad rebuilt big power transformers. I preferred the step down that had non-volatile memory.

My favorite was the HP 41CV. That was a truly awesome calculator! And someone stole it from my office at work, probably the cleaning crew. I bought a newer model, but they'd changed the RPN programming language, and I just didn't like it as much.

Still love RPN, though.
