RE: Your First Handheld?
I got my first handheld at Macy's in San Francisco in 1975 -- a Qualitron 1444 "Electronic Slide Rule." Had percent, reciprocal, sqrt & square, plus memory and an X<>Y key. What it could do blew my mind.
I had an old Monroe rotary (with the carriage that moved back & forth) at work. Still I wasn't sure I could trust a machine to do what I could with pencil and paper, so for a month after getting the Qualitron, I kept checking its results in my head or with pencil and paper when balancing my checkbook. Once a month went by with no errors by the electronic, I threw away my pencil. I researched programmables (TI, HP & others) in 1981 and settled on an HP-41 CV, and eventually got lots of peripherals and modules, joined PPC, the whole nine yards. I really wanted an LED machine and a financial, though, so in 1982 I bought an HP-38C Financial Programmable, which became my favorite and I used it and the HP-41 CV extensively for 2 decades. |
