[Coco] CoCoEPROMpak v1.0.1: 8k banking support + LED

[Luis Antoniosi (CoCoDemus)]

the full turn of the screw has the schematics for a static ram
(battery powered) cart by Tony Distefano. you write once on it and the
battery will keep it as it was a rom. but you musrt write from the
coco either using floppy or cassete.

Im thinking it will have to preload the image into some sort of parallel Flash or SRAM as accessing the serial devices, especially SD card, would be too slow.  I've got to figure out a combination I can work with.

But then, if you have something like an Arduino connected to the board, then maybe you can also use it for other interesting functions besides ROM bank selection?
