[Coco] CoCoFest 22

[Mark Martin]

I believe there was a call to bring new tech items to interface the CoCo
with, so I'm going to load up all the Arduino, RPi, and FPGA stuff I have
at the moment.  I'm also trying to line up a table from the fine folks at
Glenside to tinker at.  Would anybody mind sharing some electronics
knowledge with me as I'm an amateur on the hardware side, or any
designs/schematics that exist for microcontroller and logic device
interfacing to the CoCo expansion bus?  I do have a bare PAK card I should
be able to use to prototype off of.  I believe I may have a spare CoCo 2 I
can bring along with a monitor, although if I blow it, I'm done for the day.
