Commodore
Mechanical Adding machine Web Page


cbm/cbmcalcs/cbmcalctypec.gif Not long after Commodore started their typewriter business, they branched into mechanical adding machines, which were not too much different. These machines work by having a rotatic plastic 0-9 wheel for each digit in the number. The buttons under each digit can be used to "Add" from 1-5 to that digit, causing its value to increment, and possibly spinning the digit wheels to its left. The large button to the left resets all digit wheels to 0.

The bottom label on this model says Type-C, but I'm not sure that's what Commodore marketed it as. If you happen to know, please drop me a line!
