RPC R.P.C. Test Generator - vintage NASA electronics - Resistive Plate Chamber

Description

This is a R.P.C. / RPC test generator
It is was most likely
made
in 1974 based on the 7449 date code on the one IC.
This device came from a NASA auction.  Most items had NASA tags on them this one doesn't.  There is a very good chance it was hand made because there is no part number or banding on it.
The power cord has been clipped off but I did put a jumper on it and powered it up.  It appears to be working but I don't have a scope right now to test the outputs.
It was last inventoried in 1979 based on the little blue sticker on the lid.
I did a little research and a RPC seems to be a Resistive Plate Chamber.
A
Resistive plate chamber
(RPC) is a particle detector used in high energy physics.
If anyone out there knows what NASA would have been using this for I would appreciate knowing.
