Apart from the HP8568 I have not seen them documented on any instrument.

But a good first shot:  Try sending the command "MREAD 0" and see
what happens...

And it's not like disassembling the firmware of instruments of this
vintage is a big deal anyway...

Never attribute to malice what can adequately be explained by incompetence.
