[amsat-bb] Paccomm PSK-1 firmware discovery

[Greg Beat]

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?
