I pulled the 6309c and put it on a breadboard with 10K pullups on NMI,
IRQ, MRDY, HALT, RESET, etc. I put a 10uF on RESET as well and powered
it up...
Nothing. :-(
I tried my 6809 as well, to the same effect. I don't doubt your advice,
but it looks like I have more I need to do to get this CPU to run.
