Just a quick post about my latest acquisition: an AGFA Bezugsband 9,5 DIN 45513.
Some pictures here:
I think it was made in 1967, which is a good construction year 🙂
I came with some documentation, which I will post here for reference and archival:
Funny the documentation mentions 250 pico Weber per millimeter track width, where nowadays we use NanoWeber per meter.
Also, much use is made of time constants like 3180 µs, which corresponds with 50 Hz.
The tape appears to be in very, very good condition.
