This is a pair of PCBs that implements a version of the Apple II VGA design. Please see the Apple II VGA Project for details and firmware. This version differs from the original in that:

• It makes use of the Rpi Pico's regulator for 3v3 supply
• It allows the SYNC signal to be optionally routed to the Rpi Pico (instead of allowing Apple II bus read operations)
• It uses a fourth 74LVC245A instead of a 74LS07 for the remaining bus signals (fewer unique components)
