Subject: [stella] pin description for 6507? From: "Kennehan, Richard" <Richard_Kennehan@xxxxxxxxxxxxxxxxxxxx> Date: Wed, 31 May 2000 09:36:45 -0500 |
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 +---------+ | | | | | +---+ | | P | +-----+---+ 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. -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
