Once Again

March 13, 2017

I am debugging code across four platforms in the most desperate way imaginable 

I have a problem with something in my 1806 adaptation corrupting memory and i was trying to use avrdude to read out the memory contents but i now note that somewhere in the evolution of the circuit i started loading the output shift register only on actual I/O from the 1802. I triggers on NAND(N1,TPB) so only when the 1802 has written to port 2,4,6, or 7. In the original circuit I think /LOAD would have been accepted as well as N1. So, back to staring at code.
