Very nice. Any option for 2 player? Would you be selling these in the future? What about SGM compatibility?

Wow!  That is fantastic!  I love all this new hardware in development.  Now we just need to get some of it shipping!  :P

Great! It is already awesome!
To make it perfect you should add 32kb of ram, ay8910 support (sgm/adam emulation) and a port for a second joystick

Many thanks for your interest !

Yes for shure.

Would you be selling these in the future?

 

Yes certainly.

What about SGM compatibility?

 

I can't speak now about next prototype capabilities.

Next prototype is under processing ;)

Some new prototype photos.

No change with capabilities for now except Coleco joystick compatibility.

I imagine it is wishful thinking to add a 7800 port with true +5 VCC that can supply 100mA on pin 7 and true ground on pin 8, so you can play games with other controllers using powered adapters. Can a 7800 type controller be used with both buttons (not simultaneously, I suppose) on a Colecovision controller socket without the signal pulses that normally come from pin 8 and 5? The easiest part would be replacing the quadrature dection on pin 7 with the +5V VCC. The 7800 controllers can still use pin 8 as a ground on a CV, but I don't know how it would handle voltage/current on it if pin 8 is swinging between 4V and -0.7V.

 

May just having to stick to emulation to use the myriad of playstation, nintendo and usb PC controllers and racing wheels, like you can for atari.

Joystick compatibility is a big problem with Coleco cause it's keypad..

For now I keep original joystick connectors and later I'll make an arcade stick with keypad.

 

Yesterday I add SGM to my proto as you can see in this photo :

Prototype is nearly finished :grin:

Wow your project is starting to look pretty amazing!  I have been so tired of my old Colecovision hardware, and what do you know, a few options appear on the screen.

 

I am liking all 3 of the new colecovision hardware replacements, and plan to support all 3 of them.

 

I am looking forward to seeing what they all offer, and to tupperware my Coleco console for the longterm!
