Hello everyone, I looked at the ATARI FAQ online but couldn't find a satisfying answer. Would anyone know why the SECAM XEGS made for the French market has 2 color knobs? Is there a way to adjust those in a standardized manner or is it just about finding the best PQ on your screen? I'm attaching a picture of the MB (gorgeously restored by the tremendous Paul Westphal @ EightBitFix). Thanks!
I have in my possession a problematic SECAM board of which i have modified with 5volt ram, and it still does not work. i want to replace the bios chip with a new one on eprom. looking at the guide here: http://console5.com/wiki/Colecovision_BIOS_Replacement it does not help me at all. the guide appears to not cater for the board types i have even my PAL board does not have the same layout as described in the guide both of the boards have similar layouts to the pictures i have attached, does anyone have any info i could use to replace these bios chips with new ones? is there a guide that someone knows of that will describe the procedure for this board layout? maybe someone has the pin layout of the bios chip used, i could then cobble something together myself that will work by matching the pins from the eprom etc
Hello! I'm wondering of anyone has investigated the feasibility of modding a 2600 so that you can switch between clock frequencies and/or color palettes. The goal of such a project would be to play cartridges of differing regions on the same machine. I've seen a similar project on a Commodore 16 where the clock crystal was replaced with an Arduino, the latter programmed to output different selectable frequencies to produce a signal for PAL and NTSC video. As for the color palette, I believe that would require a swap of the TIA chip, which could be done manually if the board is socketed. I haven't studied the schematic, and a cursory search doesn't show anything useful. To anyone with the hardware experience, do these ideas seem sound? My assumption is that the only difference between a PAL, NTSC, and SECAM 2600 are the clock crystal and TIA since the game cartridge does all the video synch. Steve Guidi
