I've got 4 Y (or Wye) adapters. They have the standard 9 pin arrangement, and have the 2 branches are all pins and one end is all holes.
If I remember right form owning Colecovision in my youth, there were Colecovision adapters which let you plug in an Atari 2600 controller for the joystick and one button and a Colecovision joystick for the keypad. This let you use any 2600 bat stick (which was better than the short, flat 'shroom top of a standard Coleco stick) with any one button games for Colecovision. (The only reason I never got one was because I have a solution which worked for every game I had and still have EXCEPT QBert's Qubes and The Activision Decathlon, that is the Super Action Controller.)
Over the years, I went thrift shopping and found on separate occasions, a Gemini, a Gemini Instruction Book, and 4 different Y adapters of 9 pin arrangements. I read through the Gemini Instruction manual, and found out about the Wye Adapter (this was before I was looking for Y adapters) and that got me thinking, how do I tell the difference in the wild between the 2? Some one told me of pin testing, but I don't have the equipment or knowledge to do it.
I've got a couple of theories,but I want to make sure none of them ruin my controllers systems or adapters, because the ow of best-electronics-ca.com the repairers of Atari equipment, says be care not to do anything that will short out my equipment due to the 5 Volt connection.
If I can plug 2 joysticks in in either a 2600 or Colecoviison (a little help on which is safer?) and if both joysticks and buttons activate the character, then it's the first type.
I can't think of a definitive test for the other except if only 1 joystick moves the character in the above test, then it's. Or maybe it's a paddle game fire test, like Steeplechase or Party Mix, something where you can test 2 independent fire buttons on 1A and 1B, As well as 2A and 2B
The things I don't have for my gemini are joysticks, RF switchbox, and power cord. First I know that ANY controller made for the 2600 will work on a Gemini, so that won't be a hard test. Also I know standard pre-NES RF switchbox or an RF to RCA adapter on that useless analog RF plug on a VCR and a standard single RCA cable would do it for any RF system with a Single RCA hole out. But about power, I don't know if a 2600 JR power adapter would work with it, or if I have to get a "regular" 2600 cord, or even a special Gemini Cord.
Finally will using Track&Field controller on the Colecovision for The Activision Decathlon ruin your system? I've had temporary problems with it, but got cured when I remove it. Will it work with Carnival? (I assume left button equals left press, and right button equals right press, and there's no up and down and only 1 fire button in Carnival.)
Although not technically Y adapters because there's only 2 branches, not 3, does anyone know where I can get a lefty adapter for either the 2600 stick, or the 7800 pad (such an adapter would invert up and down as well as left and right. There might have to be a button swapping adapter for 7800 games where the concept of left and right are important than main and secondary) or an Atari-joystick-to-Astrocade system adapter, or an Astrocade-joystick-to-Atari-system adapter in either Joystick (easy) or Paddle (much harder engineering-wise) mode?,
