GrumpyTim | Calculating Machine Repair and Demonstration - Madas Model 20LZVG @GrumpyTim | Uploaded 3 years ago | Updated 8 hours ago
In this video we're looking at a Madas Model 20LZVG calculating machine (or mechanical calculator as I prefer to call them), made in Switzerland in the late 1950s or early 1960s. The Madas model 20LZVG has fully automatic division but doesn't have the automatic multiplication that some of the more advanced models had - the automatic multiplication function requires an additional counter mechanism to handle the multiplication so that part was saved for the more expensive models.
When I first got this machine it was fairly battered, it even got damaged during transport to me due to very insufficient packaging. Mostly though, there was evidence of previous attempts to repair the machine using force, which had left several parts of the mechanism bent, all of which needed to be identified and rectified before the machine would work.
In the video we'll show how to open the case and remove the register before covering a few of the parts that needed to be repaired. Then we'll demonstrate how to operate the machine along with some of it's more advanced features.
