Well, IO is back to playing mind games or else it has its first hardware computer bug. I am seeing a garbage bit getting into the system and even with a slow clock speed, I can not keep track on where it is being introduced. Guess it is time to add a single step function  to the front panel. I had planned on adding it later but now I really could use it :-) With all the Leds I should be able to figure this out...

Ok now, it is September 16, 2017 and I think that I have squashed IO's first real bug. Found that in some buffers leading to the Accumulator there were 120k resistors that should have been 12k in the transistor collector path, Opps my bad :-)   I have been running IO with the 12k's for several hours without any problems. Folks out there need to be reminded that this is all new to me and now that goes for debugging :-)

September 17 and it has been 48 hours with IO running the accumulator and PC without any glitches, not one :-) Now I feel better about wiring up more circuits and working on the Brainwarp instruction set :-)
