would need to make lots of complex state machines that would be really
hard to debug. Fortunately, it's usually pretty easy to just bolt on
a microcontroller (or build one in FPGA logic, because a CPU is really
just a specialized state machine with some logic and registers bolted
on). Both Xilinx and Altera have soft-core CPUs that are free to use
and toolchains for them that aren't COMPLETE nightmares.
I agree with that. I like the wall of paper docs, rather than
click on video to show how to <blah blah blah>. My only real gripe
with the modern logic, is to my knowledge the I/O tat is NOT 5 volt
tolerant.
I would like to use the 40 pin headers for IDE interfacing or some other
'classic' interface. That might be a good project for the DEx boards
a 5 volt interface and breadboard. Even if I can't use it for my
hardware, I still have a dirt cheap PDP-11.

PS. I need to dig on the web to if there is a PDP-10 done yet.
