The blue bible, well known as the TRM !
It was the graal for users in the 80’s.
Here is it, as a PDF file (OCR) with a separate file for the schematics.
All manuals are scanned from my own materials.
If you have some of the missing manuals (or not in this list) to offer (or sell) please tell me.
If you download something, please feel free to write a little comment.
