Dave,
One thing that might be worth trying: create a ROM that is the same as the standard NODE ROM, but with the initial 8 byte auto-run signature (87654321) replaced by something else (e.g. 00000000). The MTX should then ignore the ROM on power up, and boot normally. You should then be able to activate the ring by a ROM 7 command. Even if the MTX promptly crashes you may be able to learn something.
Bill.

Hi Bill,
This is all great and the screenshots are great.
For some reason I am not getting email alerts anymore for the boards I am interested in.
Cheers.

Dave is now hosting my note on his site at
http://primrosebank.net/computers/mtx/m ... s.htm#node.
I have just sent him an update, which will hopefully appear in due course. I think this largely completes documenting the on the wire protocol. There is still a lot of work to be done to document all the variables.
There are a number of places where names are limitted to a maximum of 8 characters. Variable names in the POST, SEND & RCV commands. NODDY page name in the SNODDY command.
Another amusing querk. If you edit a NODDY page with the NODE status messages turned on, then the last status message becomes part of the NODDY page when you save it.
