I compile custom pin files for the mesa cards often. As far as I can
tell all the source is there. I have not seen any source that was hidden
or had to be included from another source but I could be mistaken.

I was in a discussion with a friend about CNC systems. He's acquired a MASSO

his router.
My comment was that a standard PC or Raspberry Pi4 (Pi5?) and a MESA Ethernet
Interface like a 7i95 at the lowest level will run simple CNC machines like CNC
routers without fancy tool changers etc.
And I reminded him that the FPGA's on the MESA products have open source
configuration. The question asked was, and I didn't have an answer, how open
source are they really? If someone wanted to do their own PC board layout
could they build an equivalent 7i92H or is there still stuff that's
proprietary? The rest of LinuxCNC is all open. May be a mine field of very
confusing and difficult to understand information but it's there for the people
who know.
Nice as MASSO looks or some other systems I prefer the MESA and PC (or Pi4/5)
solution. But how does one justify a LinuxCNC solution for a simple CNC
system. Not a major overhaul of old iron that gets the old paper tape stuff
thrown out. But a brand new mill from the far east that is retrofitted with
inexpensive AC Servos?
