2600 Composite mod
Re: 2600 Composite mod
Its been over a year since this project was started. I'm going to try and get this project finished in the near future. I've found a few of the bits yesterday.. Still need to find the PCBs.. So might have to order some again. I really want to get my 2600 back together and have some fun with it

Re: 2600 Composite mod
Funnily enough, I still have this project on the books, I'd better dig it out and get on with it myself.
Collector of many retro things!
800XL and 65XE both with Ultimate1MB,VBXL/XE & PokeyMax, SIDE3, SDrive Max, 2x 1010 cassette, 2x 1050 one with Happy mod, 3x 2600 Jr, 7800 and Lynx II
Approx 20 STs, including a 520 STM, 520 STFMs, 3x Mega ST, MSTE & 2x 32 Mhz boosted STEs
Plus the rest, totalling around 50 machines including a QL, 3x BBC Model B, Electron, Spectrums, ZX81 etc...

Re: 2600 Composite mod
I have just bought set of boards for composite mod but look nothing like this,
using
3.3K , 2.2K resistor and 2N3904
nothings ever simple!

I've built these using veroboard, they work well enough, but time to get on with the exxos onezack4mac wrote: Wed Apr 17, 2019 9:17 am I have just bought set of boards for composite mod but look nothing like this,

Re: 2600 Composite mod
Found the PCB with parts listed..
There are a couple resistors I am not sure about at the bottom.. more of a "suck it and see" type thing. So some experimentation needed no doubt.

Re: 2600 Composite mod
I've got a couple of 2600s lined up for when you've finished 
If it ain't broke, test it to Destruction.

Re: 2600 Composite mod
I have hunted high and low, and I cannot find these PCBs
, so I will have to order them again, which means another month wait 
Re: 2600 Composite mod
You need a various pcb box. Icky probably has a label you could use once you've got one.
If it ain't broke, test it to Destruction.
