John,
You fail to also mention that the datasheet states:
“For 8 pin PICAXE chips either position may be used (breadboard wires are required between the adapter and the 8 pin chip).”
If you look at the bottom of the datasheet, the available copy (per my link at post 11, the datasheet was prepared on 5 June 2006.
At that time the M2 and X2 range of PICAXE chips did not exist.
Agreed not stated on the old-ish datasheet, however the 14 and 20 pi devices must be treated exactly as per the 8 pin devices.
Why would you think that nothing (i.e. no jumper) is required to use the AXE029 with the 20 pin chips ?
Looking also at the circuit diagram at the bottom of the datasheet it is clear to anyone who can understand a circuit diagram that without the jumper/link that the “SerialOut” connection is not available at the breadboard pins.
For me personally, reading that you are someone who has been soldering since at least 1950, and joined this forum in Dec 2015 I would expect that you can read a circuit diagram.

westaust55,
Been to N/E/S Australia but unfortunately not to the West.
Appreciate your observations.
The 8 , M2 and X2 of no concern to me.
Am using the 20M2 and it not mentioned, however AllyCat's diagrams helped figure out how to use it.
I don't want to beat this dead horse anymore.
I am still unable to get the 029 to work; perhaps I have a bad part!?!? I have two more on order, so we shall see.
Not a huge issue for me other than wasted alot of time trying to get it to work. But that is really not a big deal because I got to use alot of good advice from helpful Forum members. Some of these posts helped with the variety of "Workarounds".
Example...Inglewoodpete's advice on soldering longer prongs on the Stereo Socket.
Regarding your comments about my soldering and circuit reading.....
Was responding to KFJL's comment "don't you like soldering ?".
Since you not recognize levity bordering on sarcasm as a response to a somewhat insulting question?
I "Splain it Lucy":
I was born in the early 1940's so no soldering awards in 1950 or 2013. Not learn to solder until many moons ago when in my 50's at start of being a robotic hobbyist. Don't care to solder if I don't have to but don't necessarily dislike it.
Look, yes do struggle occasionally to read circuits ( I have no formal technical training, so this forum is usually a God send )..
My comments about jumper's are related to text in this old and somewhat complicated datasheet.
Yes, the circuit clearly shows a jumper needed, so I missed that; was too focused on the printed word which did not specify the jumper mandatory---->
my mistake!
Most all have posted helpful comments.
Disappointed to read a few insulting statements along with a mostly helpful Forum!
There was nothing helpful in your message.
