For some reason, when booting the P3, it drops the first two letters of the 'Firmware check..' message. I'm not sure if this is the P3 mainboard booting faster than the LCD, or what.

R20 replaced with a 10K part, per Colin Fraser's suggestion, in an attempt to alleviate the issues with the LCD.

After replacing R20 with a 10K part the LCD is now displaying correctly. Yay!

My x0xb0x, laptop, and Ivan's P3 on my workbench as I troubleshot the MIDI sync problem. Note the real nice square waves on the scope showing the sync pulses being sent to the PIC.

Looking inside of Ivan's P3 while the micro grabbers are connected to ground, sync in (to the PIC on GP4), and what should be MIDI out (from the PIC on GP0).
