Switchless NTSC<->PAL

Post by mythic66 »

The switching is done with a single POKE, then you have to reset the computer. The clocks are generated on the
board, so the xtal on the motherboard can be remove to make the switcher sit lower.

I have the signal generate to switch the kernal, I'm doing the little PCB to be used in the kernal socket.

The idea source was the VIC2 switcher, but I wanted mine to be compact and without relay.

Couldn't you make it generate the reset signal as well (would require a patch cable of ofcourse)?
I'm just a Software Guy who has no Idea how the Hardware works. Don't listen to me.

yes, for sure, but you will have to solder a wire to the reset path. I have free pins on the header.

At the end this will work with my memory expansion board that will handle the reset.
