Back in the 70s, VW had a competition going when they came up with a
diagnostic connector (maybe pre-dating OBD2 or J1850?) to give it a name.
An engineer that sat next to me came up with what I thought should have
been the winning entry, although I am not sure he entered it: "Debug the
Bug plug".
I wonder if anybody has heard of this in the wild?
cheers,
Nigel

To which David Barto replied:
Are you suggesting some kind of, say, portable
computer?
Runs, dodging and weaving.
I'm not sure that you could fit a complete Model 33-ASR Teletype in the
passenger seat of
the Bug. I suppose if the Teletype was removed from its stand, it might be able to sit on
the
seat, and be powered by the same generator that runs the Straight-8. The Straight-8
came with a 110-baud current-loop serial I/O interface, so it'd just be a matter of
cabling it up to the Teletype.
It'd be really hard to operate the machine while driving, for sure. It'd be far
worse than messing with a smartphone while driving :-/. But, once stopped somewhere
pleasant, you could
actually develop programs using the punched tape reader/punch on the 33ASR. It'd
definitely be
an example of early "mobile computing". (Tongue firmly in cheek).
