Personally, I would definitely do the upgrade; however -- as I already wrote -- the bugs in TOS 1.00 might not be that critical if you use the machine for games only.So I guess a 1.00 to 1.04 wold be a good choice?
EDIT: An old Atari technical note recommends increasing that capacitor, particularly if a certain type of power supply is installed. This may be the reason for different caps on boards of the same revision.
Yeah, that's pretty much what I have with the differences of no modulator (or Csync circuit ), full med instead of half, and less components inside the center box (I guess those are for the composite/rf output?).
