Italians around?

Hello all, 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, Simon Claessen drukknop.nl
