If memory serves, this was a plug-in designed for the basic HP 524B series freq
counters that were 2.5 ft cubes full of tubes and the vertical neon bulb 
decade
counters.... good for counting up to 10 mHz and using the converters to go
higher.

Fun things to use (and maintain) back in the fifties/sixties, but of no value
today except for an HP museum.

Ya hate to see any classic junk destroyed or parted out, but just who might
find it usable is a good question.

Hope this helps...
