I am checking out a couple of surplus Paccomm PSK-1 this weekend.
I was told that there was only one version of the PSK-1 firmware, BUT I have
discovered that is not true.
S/N are hand written on the PSK-1 printed circuit board.
S/N P10511

This earlier 1989 version (2.01) supports the KC Tuner function
This version of the PSK-1 will turn ON (slave operation), when the host TNC-2
is tuned ON

-----
This later 1990 version (2.10) removes the KC Tuner support and
replaces it with a Help function.
This version of the PSK-1 will NOT turn ON, when the host TNC-2 is tuned ON.
Power ON function has to be separately performed with each modem.

Interesting discovery and behavior.
Any thoughts?
