Testing the cassette interface on the TRS-80 CoCo 2 board I made.

In this video I test the the cassette interface by loading a game from my computer via it's microphone output. I didn't have cassette tapes to test if it worked with my tape drive but later that day I received cassette tapes and
have since successfully tested with the tape drive.

I just need to test the serial port to call it fully tested.

Recently I learned about the Bit-Preserve project started by James Lewis (The Bald Engineer) and decided to contribute by transcribing a pdf of the schematic for my model TRS-80 into KiCAD.(This is what James is proposing for a bunch of retro systems). In one of his talks he mentions not having a good way to confirm that the schematics are actually accurate so I thought that actually recreating the circuit board is the best way to confirm the schematic is correct.

Thanks James for starting this project!
