Apple ][ PicoVGA
This project is a VGA card for Apple II/II+ and //e computers to output a crisp RGB signal to a VGA monitor instead of having to rely on the composite output. This is accomplished by snooping the 6502 bus and creating a shadow copy of the video memory within a Raspberry Pi Pico, then processing the raw video memory contents to output a "perfect" signal.
These features are currently supported:
Generates a 640x480@60 VGA signal with 3 bits per color channel using resistor DACs
Text mode (monochrome)
Lo-res mode with no color fringing between the chunky pixels
Hi-res mode with simulated NTSC artifact color
Mixed lo-res and hi-res modes with monochrome text and no color fringing
Double hi-res and 80 column mode on the //e only
you will need the apple2vgaadapter also.
