Again, thanks @johnbeetem. Yes, MoC does seem like a fair
description. Limited protection also seems pretty accurate. I was
thinking along the lines of using the I/O for crude system
information via a couple of leds. I'll think more carefully till
I can get a safer IO interface.
I agree about the FTDI interface and their data sheets. Eminently
sensible decision IMHO. My first cpu was a 4004, I read the spec
sheet returning from Welwyn to home on the train and found it
quite fascinating. That and its big brother were used in a
terminal I had to maintain. Hate to do the same to an ARM chip!
Heck of a train journey.
"You can also get FT232H data sheets."
as you say, complete with drivers.
