Yes, I have, it can also be found in the VAX Peripheral Handbook and 
called RSP (Radial Serial Protocol).  It's _very_ simple.

Yes, but you need also a TU58 drive. A "normal" TU58 are connected into
any serial port, but the internal one from a 750 isn't connected in
the same way. So, you need to go out and find some old PDP diehard
that still have one of the external TU58's. I don't think that you can
find somewhere inside a 750 you can connect a serial port.

I think a much better idea is to write a small PC program that can
dump over programs via the console 'X' flag.
