Hi, although somewhat off topic, unless I'm reprogramming antique computers :)
...
I was wondering if anyone might know where I could find an A/B switchbox for a 10-pin JTAG
cable?
(An old-fashioned mechanical switch would work for my purposes, but I don't want to
have to try to build one :)
thanks,
Stan

Watch out doing a hard common of the grounds. It may not turn out
pretty. Also make sure there is no VCC routed up the cable.
thanks.
You might well get by with a normal serial DB-9 and some creative cable
making if memory serves. At least the 1194 stuff is only 5 signals.
Some of the jtag pinouts include break and trigger signals though.

I'd try a plain old parallel printer manual A-B (C-D) switch box.
They're still available and fairly inexpensive. You have at least 10
independent conductors--and many of these switch all 25 conductors.
