It's output of a digitizer (but not that old). I was also wondering about
the reason for this limitation (maybe the design is ~20 years old).
Hi,
I have a binary file containing 3 byte float values (big endian). How can I
read them into python? The struct module does not work, since it expects 4
byte floats.
Any hints?

I have a binary file containing 3 byte float values. How can I read them

Not yet. It's seismic data, that implie

Personally I would expect simple counts (since other seismic formats don't
even think of using floats because most digitizer
