Intellivision Flashback Controller Adapters

Out of the box, the Intellivision Flashback controllers, while excellent, are not wired correctly to work on anything other than an Intellivision Flashback (thanks AtGames). But fear not, there is a solution!

I have two different types of Flashback controller adapter cables:

The first adapter type allows you to use Flashback controllers on your Intellivision II or Sears Super Video Arcade (the consoles that had the easily removable ‘DB9 plug’ connectors on the controllers). These are 6 foot extension/conversion cables, with a male DB9-pin plug on one end, and a female DB9-pin plug on the other.

The cost is $17 per cable, or $32/pair + shipping.

The second adapter type allows you to use Flashback controllers on your original model Intellivision, INTV System III, INTV Super Pro System, RCA Tandyvision, GTE/Sylvania Intellivision; basically any version of the Intellivision console that had the “hard wired” controllers. These are approximately 18 inches in length, with a male DB9-pin plug on one end, and a 9-pin ‘motherboard/SIPP’ connector on the other. To install these, you need to remove 6 screws from the bottom of your Intellivision console, take the top cover off, slide the original controller connectors off the motherboard pins, and slide the adapter cable connectors onto those same motherboard pins (the adapter wires are routed out the same holes as the original controller wires). Put the top back on, and you’re done. It takes about 20 minutes from start to finish. You can then plug in your Flashback controllers with ease.

The cost is $34/pair + shipping. These are only sold in pairs.

A big thank you goes to Intellivision Productions for loaning me a prototype Intellivision Flashback controller to disassemble and test in order to work out a way to make them compatible with the original Intellivision consoles – for us long time Intellivision fans!
