|Model:||LDB 8451/00 Promotional Calculator|
I know for a fact that "LDB 8451/00" is a Philips type designation
for I've been a technical writer for a while. I do not however
know what kind of product the LDB 8451 is. What you see here
however is a plain calculator with memory, percentages and square
roots that is mounted on top of a Plexiglas Video 2000 cassette.
The cassette has the words "CLS communication logging system".
All this would lead me to presume that the LDB 8451 was a system to log communication (ATC messages?) on special video tapes.
