as I am in the process of restoring a Olivetti Programma 101, Jim
pointed me to a bunch of documents on the logic in this machine, all in
italian. The Programma 101 is build using Resistor-Transistor-Logic, and
the schematic representation is not one i've seen before. So I've
decided to translate the docs to english and google translate can be of
some help here, but a lot of the technical meaning is lost.
By looking at the schematics and the boards themselves I could solve
some mysteries, but I could use some help in translating.
Our machine seems to have intermitted problems and I think they are
caused by bad contacts in the backplane, but to be shure, a good
schematic and explanation of the workings is a tremendous help.
Is there someone able to take a look at the originals and my rudimentary
translation and suggest improvements?
Met vriendelijke Groet,
