[for the line eater...?  (Another urban legend?)]

I do hope my request isn't too mundane... it's hardware.

I have an OLD A1000 (late '85?  No EHB) with:
   an external drive
   total 2.5M RAM(512K in machine, another 2M on a Microbotics Starboard2)
   - and now - a 1300 Genlock.

First the Genlock-specific troubles:
   The top inch or so "twitches" to one side.  Sync troubles, I presume.
I looked inside, but resistor R55 was already gone.  (From the factory
or from the dealer, I don't know.)  Why might it still twitch?  The
camera? (I intend to borrow another one to check that...)  The power
drain on the A1000?  A chip in the A1000? (I haven't yet made the A1000
video mod for a nicer broadcast signal given in Amazing Computing
(2:7?).)

Now, the duller stuff:
  The genlock does odd stuff to the screen colors under certain conditions;
Popcli blanks out more red than the previous grayish color (oh yeah, I'm
using a Sony 12" trinitron monitor - CPD-1200?.)  So, right now my boot
colors are dark gray, red, then white.  SOMETIMES, I have gotten pale
green and such, generally without the genlock.  You can tell what this
is leading to, right? - could a kind soul email me the A1000 boot
sequence colors and explanations that have been gone over before?
Thanks - sorry to ask again.
