Awesome firsts 
Rek, I'll post a picture of my very first calculator that only added and subbed in decimal. It was purely shift register based.... superisingly wasnt that slow (took between 12 and 40 ticks, lol what is this 'sync' word u mention? No idea! Lol) .. could work on 0-99 but inputting numbers was a hassle. (pressed buttons x amount of times for a given x value in a tens or 1s place.)
