#WLAMF no. 36: Antique Calculators

[tacit]

I first went off to college in 1984. (I say "first" because I've had a somewhat checkered college career, with many false starts.) On the occasion of my going off to school, to learn (or so I thought) computer engineering, I got myself a programmable calculator: a Radio Shack EC-4004

I have a Casio FX-570c from 1985. It uses a LR44 battery. I finally had to replace the battery a couple of years ago.

Funnily the wallet-case it came in had started to plasticise and degrade; the calculator itself works just fine!

One reason I got it is that it does binary/octal/decimal/hexadecimal and I used to use it for base conversion :-)
MODE 1 to enter base-n mode
ENG to enter Decimal mode
100
ENG<- returns 64h
SHIFT-ENG returns 1100100b
SHIFT-ENG<- returns 144o
