I didn't get around to examining the wiring in my VAX last night, but I determined the wiring from the TU58 manual, anyway.

When I was debugging the connection between my VAX and tu58em on my Mac, I ended up buying an old serial protocol analyzer. Notably, I specifically avoided one with the same type of tape drive; I got one with a nice, reliable 3.5" floppy drive! ;)
