You're very kind, Al.

You'll find the implementation of the serial port a bit nutty, but it works!

I plan one day to turn the 'echo' program into a boot loader, which can then load in a 'checksum boot loader' over the serial link, which can then load in MS Basic. Just like the good ol' days!

Even though I run the LEDs at only 100uA, they are still a bit too bright and dazzling. A testament to the efficiency of modern LEDs?

Enjoy!
