Hello. I'm currently working on some "diagrams" for standardising the procedure of capturing tapes for our 1000+ tapes project and thought of using fonts from those printed manuals used in the 70/80s, as a gimmick and as some photos have that vibe. If anyone knows of such fonts or similar ones, preferable free, I would be very grateful for those. If someone knows links to PDF or scans for manuals from that time period, that would be very helpful too. Thanks in advance for reading and knowing something.
