[TenTec] Paragon 585 mystery board

[Bill Acito <w1pa@hotmail.com>]

I’m working on a Paragon and it has a small, extra board, 81420, mounted up 
close to the display.  The silkscreen and connectors match the rest, so I’m 
pretty sure it’s Ten Tec built, but I can find no references to it.

There is a classic Ten-Tec-keyer “orange spot” switch mounted on the top case,  
and it has a 555timer  and 358 op amp, as well as a mini-piezo/speaker  on it.  
I suspect it might be a 10-minute audible timer.   Anyone every seen one of 
these?
