I cut out the part of the 2600jr circuit board that contains the RF
modulator and replaced it with perfboard, so that I would have lots of room
for not only the composite video mod, but future mods as well.
So currently, my circuit board looks like this, with the section marked with
a "P" as perfboard
+---------+

Unfortunately, pin 1 and 2 of the 6507 extended into that region that I
chopped off, and now the Atari won't work.
I consulted the atari schematic diagrams that someone posted on the
internet. It shows pin 1 to be the RESET pin. Should this be tied high or
low voltage?
Does anyone know what pin 2 of the 6507 does? It is not mentioned on the
schematic.
A complete pin description of the 6507, RIOT, and TIA would be a great
addition to the 2600 programming faqs.
