There was someone recently who discussed having the schematics but its something that is still supposed to be a clandestine schematic.

Thank you very much, Christopher, for the info on UTG and the links to the UTG binary. It would be really cool to see a video of the two Vectrexes communicating and being played. I'd settle for a video of UTG using the VecLink. Frankly, I'm not sure if I can find the cable I hacked together back then nor Alex's schematics. Hmm, a VecLink cable shouldn't be too hard to do and plus the UTG binary available a video should be in sight. Let's see who's first to post a video...

From Atariage, by Rob Mitchell: "VecLink (Two Atari joystick cables with pins 1,2,3,8 wired together). Link two Vectrex consoles together via controller 2 ports." This was also discussed previously on VGF a couple of years ago.

IIRC, they were Sega cables and there was at least one resistor in there but it was a very simple circuit. (I think Sega was important because one of the pins on Atari joysticks was not connected?) But if Rob got it working I may be misremembering...
The binary with dual play/VecLink support was definitely never released, just single player.

I could not find where Rob ever said it was just connecting 1,2,3, and 8. I did see where Chris Tumber said it did include 2 resistors as an alternative to using a chip.

Hey, the VecLink schematics, great! Did you "design" the schematics or where is it from? Anyway, thank you very much for posting the schematics, binarystar! :-)

I have no idea if it's right or wrong (not tested it) but it seems to be the same design as mentioned above. It was passed on to me when I was looking for this info previously. I hope I'm not pissing anyone off by sharing it but it's pretty much what is described above anyway (2 DB9s and a couple resistors).

Looks familiar - That's probably it.

Great info guys, will definitely look into this.
I was thinking of hooking up a cheap Arduino to those 4 pins and somehow (Serial over USB like the Arduino likes or something similar) sending the Vectrex "4 pin serial protocol" data to a real PC. Then using the PC to send this info over IP to another Vectrex connected the same way.
The benefit would be that
1. The Vectrex code can be kept as simple as possible, as long say the coordinates and bearing of your ship and your missiles can be transferred, we are all good.
2. As stated, you would not need 2 Vectrexes (is that the plural of Vectrex? :-) ) to play a PvP game.

Unofficially, it was agreed that it would be Vectri several years ago.

I'm thinking of selling my NVRAM adapter. It comes with a Vectrex to USB Serial bridge. It can also run Basic using PC serial terminal software. The NVRAM gives an extra 17K of RAM.

In the latest DVE download made available by Chris S very recently , there is a subfolder called "other" and in there are two binaries called DualTV1 and DualTV2. (may be these files were in the previous DVE too, but I had never downloaded it before). When you run DualTV1 it says DUAL VECTREX TEST as the title, and the next screen shows WAITING. DualTV2 just seems to hang - that's probably because I haven't connected two Vectrex consoles together to each run one of these programs. Chris T, can you remember if these are your programs?
