  1. I'm building a home made Colecovision controller. Base is Dreamcast arcade stick, with Seimitsu LS-32, and 30mm screw in buttons. I'm looking to have a control panel overlay printed, but need artwork.

     

    Control panel is 11 1/4 wide by 6 5/8 tall. Or 28.5 cm wide and 16 cm tall. I was thinking of putting Colecovision logo on bottom left say 1 inch in from side and 3/4 inch from bottom. Logo should be about 1 inch tall. Top part of can have silver lines or whatever would make this look Coleco'ish, but can't have logo due to joystick, keypad, and button cutouts. Most of control panel will be black. I'm still up in the air about dyeing off white controller base black.

     

    thanks

  2. New system board is a great idea. New new shell would be cool too. Perhaps remove controller holder (CV mini). Put controller ports on front of system, add on/off led, upgraded video output options, provide better on/off button, fix memory flakeyness.

     

    Not sure if you guys have seen the "Omega", a Neo Geo MVS MV-1C (arcade board) made into a console. The guy who created the Omega put in new video - RGB, component, s-video, composite, built in AC to DC power supply - no more brick, added new bios, joystick ports.

  3. I just played both Activision tennis and ice hockey, I remember from quite a few years ago, and they look perfect. Boxing seems too hard for me to follow (sad), but thanks for the recommendations.

  4. Here it is 1/2 way done. Need to order some resistors to add the 2nd fire button and switch to Genesis line cord in order to wire up. As a basic Atari joystick it works fine. I couldn't find my old Turbografx pad, so I used this old pcengine one. Its easy enough to reverse as nothing is damaged during the install besides the Atari cable which came from broken joystick anyway.

     

    I've added some diagrams in case anyone else ever wants to do this. Please note my pin numbers don't match the real pin numbers of the IC/board. These are from the person who needs to solder it perspective, i.e. facing you.

     

    thanks,

  5. hi I just bought a Sears Heavy Sixer and I'm getting some strange Video.

     

    with Space invaders (Sears Tele-games cart) I get horizontal bars on left hand side. With Missile Command (another sears Tele-games cart) I get two columns of blue dots on left hand side. Combat game (tanks) is ok, and Maze Mani is ok.

     

    Does someone know how to fix?

     

     

    I use quick drying contact cleaner on all the contacts, but same results.

     

     

    Thanks,

    Dave


  6. Yeah, took a while for me to come to this same idea. I was looking at Atari joystick pcb and it doesn't seem to have any active electronics, so just wire turbopad like original. I might have to cut some traces on the Turbopad pcb and wire some things that might be missing, but that seems ok.

     

    Now for the better part of this. I don't like the Colecovision controller either :(, and since it has two button and I think some Atari games use two buttons and the turbopad has 2 button I would wire both of them in.

     

    Does someone know of a two button Atari game and Colecovision game to test with?

     

    I plan to wire a db9 at bottom of coleco controller, so I can use its keypad, but use this Turbopad for the rest.

     

    thanks,

    dave
