Did you know? Color Bar Generator DIY kit on magazine

Recommended Posts

I searched the forums, but I didn't find this mentioned.
I just found out that the "Color Bar Generator" cartridge from Videosoft was published in the "Radio Electronics" magazine as a DIY project.
The article can be found in the August 1984 issue, pages 41-43 (you can download it from here).

In the article by Jerry Lawson and Dan McElroy there are PCB layouts to etch your own board, a list of components (which only consists in the eprom and inverter IC) and a brief overview about the VCS hardware (the TIA is referred to as VIC, which stands for Video Interface Circuit and it's how it is called on VCS documentation from Coleco ) and the Color Bar Generator functions.
There's also the address and pricelist for ordering from VideoSoft.
You could buy the fully assembled cartridge, the kit or, interestingly, the source code listing, in case you wanted to burn your own eprom.
