I've followed Jack's "Embedded Muse" from its inception--interesting
ideas come through frequently and the tales of experience are worth the
look if for no other reason...

Not directly applicable to PLCs but if you're writing embedded code or
otherwise involved w/ hardware/software interfacing, it's good stuff...

From a distant past, did a lot of work for Remotec on early versions of
what evolved into the Andros Mark V robots. The specific version we
shipped was for man-replacement use in commercial nuclear power plants
and was equipped w/ a manipulator or optional instrumentation package.
It was three Motorola 68k's (two onboard/one operator console) in VME
bus running under CP/M w/ the control software written in Forth...

That was about 10 years prior to this press release when Remotec was
still a relatively new startup...
