Well, I got the visual 603 working...there is a 1.5uF capacitor
(non-polar high frequency) located right between the flyback transformer
and the horizontal deflection coils.  It was fried...I replaced it with
a ceramic monolithic capacitor, and the terminal worked!  But after a
tilting it on its front (to adjust something), I cannot get it to work
at all.  When turned on, it sometimes beeps (and flashes keyboard led's)
ONCE quickly, and sits there -- no high frequency hum from the video.
Sometimes, nothing at all happens.   Any ideas?  I'm looking into possible
loose connections (since I had to remove the video board to fix it) which
may have resulted from tipping the terminal, but I dunno...these things
ARE very unreliable....Thanks to all those who responded to my first plea.

   This is a test of the emergency signature system.  Were this an actual
   signature, you would see amusing mottos, disclaimers, a zillion net
   addresses, or edifying philisophical statements.  This is only a test.
