Repairing roller controller buttons?

Wed Mar 15, 2017 11:17 AM

So I recently acquired a roller controller in pretty bad shape (it was filthy), anyway I got it all cleaned up and amazingly the optical sensors still work fine, the buttons on the other hand do not. I managed to open the buttons (you can remove the black piece by snapping it out of the top) and found that all they are is little grey rubber contact buttons (like you would find in say a SNES controller). It looked like the rubber domes had become worn/brittle with time, two of them were torn. 

 

1. Does anyone know of a replacement for the button contacts? (the grey rubber piece) 

 

2. Does anyone know of a complete replacement for the switch? (as in de-soldering the old switch, putting a new one in). 

 

(I can post pictures if needed)


Colecovision RGB mods?

Fri Mar 3, 2017 5:10 PM

I apologize if this is a redundant thread, but I was having trouble finding information on this. While I think the f18a mod is cool I mostly use an XRGB framemeister for upscaling older systems and currently don't have any displays that accept VGA input (it's sadly getting phased out of modern televisions). I know there are now 2600 and NES RGB mods but I wasn't sure if there was a Colecovision one in the works as well. 

 

  1. Does the F18A mod support RGB Scart or is it VGA only? Are there any plans to produce an RGB scart version?
  2. Is Yurkie still working on his RGB mod? I saw the youtube video which is from 2015.

I realize that translating VGA to RGB Scart isn't that difficult but the main issue is 'sync'. VGA has multiple sync lines while RGB scart has one and I imagine that could cause issues. If there is a good/reliable method to translate a VGA signal into an RGB scart one I would be interested in hearing about it. 

 

Thanks. 

 

EDIT: Of course I find this (UMSA ultimate scart adapter) right after posting this thread. Does anyone have any experience using this in combination with the F18A mod? 


More accurate switch replacement?

Fri Feb 24, 2017 4:47 PM

I think everyone is well aware how finicky the power switches on the coleco can be, and that there are numerous ways to address the problem. I have seen the popular mod where people replace the switch with a 'rocker' type switch, but I feel like there has to be a DPDT slide switch that is closer to what the Coleco originally used. Just some cursory searches on ebay I have found:

Or a more general search:

Has anyone had any luck with sourcing something like this (either through ebay or aliexpress)?
