This is a prime example as to why nobody should bother with an old frequency counter in unknown condition, with modules like this who needs someone else's problem? I have one from the 70s or 80s that I inherited, but I know that it works, or at least it did the last time I used it three or four years ago. Frequency counter, with nice display $9, why even try?
 The reason I mentioned it is I ran into a guy about 2-3 hours South of me on fleabay who is trying to sell a bunch of old test equipment from the 1950s through the 70s, including old signal generators, VTVMs, scopes, and frequency counters, all of it beyond premium priced, and all untested, so basically glorified e-waste. If that isn't bad enough he actually thinks that old sewing and knitting machines are worth money, which is interesting given that the thrift stores can't seem to get more then $20 for one.
