Thank you. I'm not sure whether you refuted or proved my point. To be fair,
after my last message I found an 84MB file and downloaded it, which seems to
contain everything including the kitchen sink. Lots of stuff written in
Java, some in C, and some in probably Arduino lingo. There was one file
named thermoplast-direct-drive.asm that does not appear to be human-readable
source. Maybe .asm means something else to some folks. I may or may not be
able to find what I am looking for in this pile, to wit:

1. How tempreature and feed rate is regulated in RepRap.
2. What sort of protocol is used to control temperature & feed (simple
on/off?)
3. Minimum requirements for a 3-axis machine to be used for 3D printing with
available CAM software & Mach3 or EMC2.
4. How to minimize the odds of being bitten on the butt if I start building
support hardware.

I suspect this is sort of a snap-shot dump of available files on some given
day, dependent more on who happened to be available to contribute to the
pile than on any sort of usability plan. But maybe that has always been the
way of all flesh in the open source world.

Umm... did you see the section "The Ever-Controversial File Section
(These are our sources folks!)". They do provide sources, though as
they note they are for a proprietary ECAM program that only works with
a single PCB house. While it is not ideal, it is open source. That
board design is different, but it is based on the satndard Gen3 (hence
"Gen3 remix") so you can also look at the sources for the standard
Gen3 boards from Makerbot, which have Eagle files available.

That said, virtually everyone in the community will tell you to avoid
Techzone, and by all means avoid Gen3 (whether Techzone or Makerbot)
at this point because it is horribly obsolete.

The two sets of electronics that I recommend are RAMPS and
Sanguinololu, both of which provide Eagle files for the board sources.
