  1. A pair of driving controllers were packed in with each Atari Indy 500 / Sears Race cart .. originally released the first year 1977. Cost was $40 then. i did not understand how they worked until I plugged them into the Vectrex running the controller test function .. many years ago: They are rotary digital switches which create button pushes called Quadrature encoding ..
  2. I am trimming a small amount of rubber from the bottom of the plugs to fit the Vectrex controller ports. They are 9 wire through cables and will work with all 9 pin controller port systems.
  3. I just received this in the mail .. one off eBay UK auction .. they are a little longer than 21 cm long. I will trim them to fit into the Vectrex and use them for custom controller setups.
  4. I just received this in the mail .. one off eBay UK auction .. they are a little longer than 21 cm long. I will trim them to fit into the Vectrex and use them for custom controller setups. I’ve never seen these before ever ..
  5. Does anyone know of a source for the controller port harness connector and pins? Looks like I will be rewiring some controllers ..
  6. FYI: this is the F8 cpu I received from China: F3850 ebay item: 131952258626
  7. Success! After replacing the video ram and cpu I got it working! Then your suggestion to glue the plastic about the ribbon cables worked. The secret is to bend up the connector to 45 degrees from the motherboard. That gives a better angle to insert the ribbon cables. My wife helped hold the top metal shielding while I worked underneath it. See pic.
  8. I wish there was a clamp down socket into which the ribbon could fit. That would be the perfect solution.
  9. Any advice on sliding the ribbon cables to the cart slot back into the mother board? The metal tabs want to separate and not go into the connector. this was not a problem on the model 2.
  10. Q: is there a better scan of the diagnostic manual somewhere?
  11. Ok .. I’ll glue the disc back in place. Thanks for your site and efforts.
  12. there was something rattling around inside one of my carts. So I opened it up and found a small black disc cover .. Q: what is it for? Q: is there a collection of game manuals somewhere?
  13. Again I totally disassembled this bank of 5 pushbuttons .. I had it apply detoxit to all springs before reliability restored .. Now System II together and working. Note System II buttons are all normally closed, momentarily open with the exception of Reset which is momentarily closed, normally open.
