What I did when programming mine was to solder several inches of solid 24ga
wire (telephone jumper wire, because that's what
Create a resistor pad with a trace connecting them. When you're done
programming you cut the trace. If you ever need to reprogram you can solder
a zero Ohm resistor on and off. See this link for an example:

Haven't had a chance to build more than the one, yet, although I did manage

Next is someone (I would love to take a stab at it sometime, but it
probably won't happen soon) actually modifies the cad files to provide a
better way to pull PORT_EN up for cpld programming. It's only a one time, 5

Quick update:
Well, the castellated boards look good after I deburred them. Took about 30
minutes to fully assemble one with hot air and solder paste. If I can make
a solder mask I think I could do it even faster. Should be able to do
several at a time in the $15 toaster oven once I get rolling bu
Note, those directions are just the latest versions of everything I could
find. But as far as I can tell, and I think Stephen said as much in a post
sometime, that all the updates take the form of a full write, meaning you
can use any update also as a fresh/initial load or downgrade, not just to
up
The CPLD load is coded April 24, 2011 (no rst). The REX SW version is 4.9.

Is there an opportunity to get at least 3 of the "new REX" ? I would like
to update my M100 and 2 M102 with REX (I've already one running in my
M200).
Additional question: What Revision you're using for the generic
programming?

The figtronix boards are castellated out of the box so we already know it's
doable at least at oshpark.
As for adjusting the layout, I always assumed one of us would just do it
ourselves rather than ask Stephen to do it for us.
The cad files are available (thank you Stepehen) and the software to

Josh,
Castellation was easy but I am not going to verify it buy buying it and
building a board. I have shared a design now on Oshpark that should be
correct for castellation. Other changes would have been more time
consuming.
I agree that the sanding thing takes a lot of effort. I used power too
Success! I have a working REX built from the parts Greg sent. Turns out

Wire. 0.02 but the size actually is not that important for the techniques
used here. Paste seems like a lot of work and expense for not much benefit

It's my design of course; when I did this board back in the day,
castellation was not available from a cheap board shop I ordered from. I
have actually never used Oshpark for a REX board, yet.
I use a grinder to quickly deal with the extra fibreglass.
