Launch year
Calculators launched 1980 to 1985
The LCD arrives. HP's landscape Voyagers launched in 1981 and 1982: the 11C, the 12C, the 15C, the 16C and the 10C. The HP-41CV of 1980 and the 41CX of 1983 built memory, the clock and extended functions into the 41. These run for months on button cells or N cells and keep their memory with the power off, so the checks are mostly about leaked batteries, a complete display and keys that register once. The 12C from this era is still made today, so check its battery to see which one you're looking at.
