2600 Composite mod
Re: 2600 Composite mod
That looks pretty good for the simple transistor mod. What monitor is that ?

Re: 2600 Composite mod
It's a Dell 2005FPW that I was given by a colleague. It has VGA in, DVI and composite, which is a bonus, however it doesn't do 15Khz, which is a shame as it's a really nice display, 20" too.exxos wrote: Mon Apr 29, 2019 12:07 am That looks pretty good for the simple transistor mod.

Re: 2600 Composite mod
Just ordered the rather expensive RGB mod
Also been adapting my video mod to incorporate the new super output buffer chip thing which is impossible to get hold of
This sort of makes the middle chip little bit pointless. It does merge the chrome and luma though.

Re: 2600 Composite mod
Is it possible to get the silkscreen component markers moved so they are easier to identify pls? It was difficult working out what went where as many parts were marked down from where they should be (D1 etc) and some are sliced in half.exxos wrote: Mon Apr 29, 2019 4:55 pm Just ordered the rather expensive RGB mod![]()

Re: 2600 Composite mod
I don't take any notice of the silk screen... I did mark it up here https://www.exxosforum.co.uk/forum/viewt ... =30#p20848 where all the bits go.rubber_jonnie wrote: Mon Apr 29, 2019 5:11 pm Is it possible to get the silkscreen component markers moved so they are easier to identify pls?

But either way, no, as I already ordered the boards

Fair enough! That pic is good enough though, works for me.exxos wrote: Mon Apr 29, 2019 5:34 pm [

Re: 2600 Composite mod
I have been toying of getting a used dell monitor or something with s-video input as my monitor is a bit crap.. though there isn't anyway to know how good another monitor is without trying it 

Re: 2600 Composite mod
Revised PCBs just came 
Started assembling one, though I realise I'm still waiting for the main output chip to arrive

Re: 2600 Composite mod
So annoying...

Re: 2600 Composite mod
Finally got round to ordering the chips from the previous version, too many projects, too little time.
If it ain't broke, test it to Destruction.
