RE: Early Continuous Memory Models
Not a calc, but a small computer design I was working on in 1986 with an 8Kx8 CMOS SRAM-- It had a 10uF capacitor on the RAM's power, and I shut the computer down at the end of a work day, and when I came back to it the next day (16 hours later), all the data was still there. I had totally removed the battery.
