I think I've made this comment before when this type of equipment has been mentioned on the list,
but as it's being mentioned again:
The 524C is a tube-based NIXIE-display digital frequency/period/event counter,
the 526B is a plug-in input module for the 524,
and IIRC the 560 is a printing recorder for use with the 524.
In my opinion, it's a reasonable acquisition for a computer museum as an example of
tube-based digital technology from which the 1st generation of computers were built
(seeing as how tube-based computers are a tad difficult to come by these days).
If you're an HP collector, the 520 series was HP's first step into digital technology.
