And make it a way to disable the onboard piezo. Alternatively, consider copy the rev3 boomer circuit and add i2c header.

[rp2040] Buffer Full Assertion

3

sending a bunch of LED on and off commands, eventually, get a buffer full message: ` assertion "buf_ctrl & USB_BUF_CTRL_FULL" failed: file "C:\Users\balde\Documents\Pico\pico-sdk\lib\tinyusb\src\portable\raspberrypi\rp2040\rp2040_usb.c", line 225, function: sync_ep_buffer `

I think there is a back powering issue that is causing the RP2040s BOD to disable them? In practice, this is not an issue since the Mega supply is controlled...

On 65C02, PLCC32 socket, dip switches, and QFN consider larger pads. Just hard to hand solder as is.

When you have time, can you provide some comments on how the PIO code is supposed to work? We're getting far enough away from its creation, I don't fully remember...

[IWM Board] - Joystick circuit Missing capacitors for NE556 circuit

PDLx signals need 22 nF capacitors connected from PDLx to ground.

Need to verify if a card asserts /DMA whether or not MEGA gates the PH0 clock to the 65c02.

The Apple II schematics (and PCB) have unique solder jumper symbols. It would be nice to have similar symbols for use in the schematics.

Apple IIc PAL is mis-aligned

Symbols are not on the correct grid. :(

I noticed while fixing #132 that the schematic symbols reference `Apple IIc Schematic Symbols` and not `Apple IIc (PAL) - 050-0093-A Schematic Symbols:`. I need to investigate why that happened....
