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 :

or this vidéo :

 

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!

Any chance of an SG-1000 adapter or is this gonna be CV only?

Sorry no SG1000 adapter, this would increase complexity and price.

Maybe I could build a FPGA SG1000 after. ;)

Most SG-1000 games have been ported to the CV and there's another group of games that have been ported by Mystery Man that will soon be sold thru the AtariAge store

Hi

Projet is not abandoned !

I'm currently working on the new (I hope the last) PCB.

You can look at some preview.

Are you releasing this as an open source project, or is the firmware closed source?

I don't think about that yet.

For now I have issue with quadrature.

I have to implement it in cv_ctrl.vhdl.

Any idéa ?

HBVision have been presented during a french retrogaming fair.

This is not the final housing but now we are very close.

Awesome work. If you keep the beige housing, there will be a huge run on the ADAM beige hand controller which should make modders who add ball knobs and straighten the cord very happy.
