There's always another way but Jim's mission was to make it possible for Joe Ham to build it with his soldering iron, resin core solder and not have to use anything stronger than a pair of reading glasses.

Jim, what amplifier functions are being divided across the eight independent
microcontrollers?  For example, does one exclusively manage the T/R
function?  Perhaps another is dedicated to monitor power supply parameters,
etc.?

My 8877 amp uses an Arduino Mega 2560 but I cram the code for all functions
into one loop.  To make this work with one microcontroller, delay commands
are invoked by comparing time registers. The main loop never stops running
at full speed no matter what delays are present.

Within the constraints of memory, it's possible to load unrelated programs
into the same microcontroller.
