I was thinking of using HEX inverters and opto isolators that basically
are two unidirectional circuits back to back.

Works in simulation but do not know how well it will work in the real
world :-(

I want to opto isolate the JTAG programmer interface from the real world
as I may otherwise and with Murphy's Law help blow up my programmer :-(
