2600 VCS Adapter Mod

You could probably run a wire from the composite in pin on the cart slot to the composite out on the video mod. You will most likely have to play around with it so they don't interfere with each other though.

No way to do it without moding the 5200 though eh?

Well, if you are already modding the 5200 for composite out this would just be one extra step. But yes, you do have to mod the 5200 itself.

Ok, so give me a little more detail on this. I could then just mod my 5200 to always allow for the adapter to output composite. Can you draw me a schematic? Tell me what line to run a wire from, you cautioned, should I include a swtich? What if I was never planning on using standard RF video again. thanks!

OK, just let you know, I haven't done this personally but looking at the schematics this should work.

 

Connect a wire to pin 24 of the cart slot, then connect a 1N914 diode to the wire with the anode toward toward the wire. Connect the cathode end of the diode to the middle of your composite mod. If you are using the composite mod from the 5200 FAQ, connect where the arrow is pointing:

                             o+5V
                                 |
                                 |  +
                                 |---|(----,
                                 |  100uF  |
                                 |         \/ GND
                       |         |
                       |         |             10uf
                       |         |---/\/\/---,--|(--,
           CR1  750    |   1.6K  |    10     | +    |
   Sync --|<]--/\/\/-, | ,-/\/\/-`           |      \/ GND
           4.7K      | | |        ___/-------`
 Luma 3 ---/\/\/-----|\|/|     Q /|/c\
           9.1K      |---|------(b|   )                   RCA jack
 Luma 2 ---/\/\/-----|   |       \|\e/          75        __
           18K       |   |           \-----,---/\/\/-----O__ LUMA
 Luma 1 ---/\/\/-----|   |  2K             |             |   OUTPUT
           36K       |   `-/\/\/----/\/\/--`         GND \/
 Luma 0 ---/\/\/-----`           |    75
                             GND \/

 

The cart slot numbering as you look at it from the top front:


36                 19
 oooooooooooooooooo
 oooooooooooooooooo
1                  18

 

I hope that helps.

I'm using the mod that was sold on ebay, it was a plug and play deal, just one or 2 wire clips to some pins, and a chip removed and plugged into a daughter board. Here might the wire go on that mod?

 

thanks

I haven't seen that one, do you have a pic?

Hmm, mostly surface mount stuff. You are probably going to have to connect the cathode end of the diode to the pin that the yellow wire is plugged into. This should give you a picture, whether it is a strong enough signal is the question. It also won't work with an S-Video connection, only composite.
