I’ve a few 4-bangers from the early 70’s, a period where manufacturers where experimenting with different designs, technologies and form factors,
I love the early Sharp calculators, they were the first to use CMOS (EL-801) the first to use LCD (EL-805 with DSM LCD*). With Busicom for which intel developped the 4004, they were among the firsts to use microprocessors in a calculator with the Rockwell PPS-4 in the programmable PC-1001 in 1973.

Now, what do you think of the design of the Sharp EL-112, 812 and 814 from 1973?

Note: the EL-812 is the little sister of the 112/814 sharing the same design in a smaller form factor and came a bit earlier, in 1972.
