| The attempt to restore a Programma 101 to working order | |
| Alle Projecten - Project Toevoegen | |
Our Olivetti Programma 101 has been sitting idle in a cellar for at least 10 years. Because of the way the machine is build and its age, all the mechanical parts have gummed up. Grease and oil have turned into goo, including the various belts. so checking and fixing the machine is only possible after thorough cleaning and lubricating the machine and providing new belts. Only then are we able to check if there is something wrong with the electronics of this calculator.
Mechanics
The mechanics is divided into some assemblies, fixed to each other and the chassis with sometimes hard to reach screws. It is the earliest known instance of a RISC processor ("Reversed Italian Screw Construction"). Where you would expect to find the head of the screw, you find the other end. So for some screws you need to stick a very long screwdriver completely through the assembly to reach it.
The units are:
- the keyboard assembly.
- the printer assembly.
- the servo assembly
- the card reader assembly.
- the motor.
- the main cooling fan.
