[TenTec] Jupiter Query

[William Evans]

I just acquired a Jupiter on that big auction in the sky, and since  
it did not come with a manual, I have called Ten-Tec and ordered  
one.  But I have some questions while I am waiting for the manual:
1)  Software version 1.02 b4 is installed in the radio... this is  
evidently the first version they came out with (Yes, it has a red  
dot, for those who want to know).  I know I can go to RFSquared and  
get the latest version, but what about the versions between 1.02 and  
1.28?  Where can I get those to play with them?
2)  Since I do not have the TT power supply, would a 20 amp supply be  
enough?  And do I need the magnetic circuit breaker?
3)  What else do I need to know to get started, or does anyone have a  
bunch of hints as to the best way to operate with it. (I am not the  
best on CW, and most of my operation is on SSB, with gobs of SWL  
thrown it for fun)
