What have you built or do you want to design to go with your replica 1

I've seen this before especially with solderless breadboards. The contacts in the holes don't last very long.

Usually the way I trouble shoot is to take the address or data value that is wrong and compare the bits to find the difference.

Man, that Woz monitor at 19200 baud is just so fast compared to the original 6820 monitor.

Howdy...

I'm trying to learn Eagle Cad.
Could someone who actuallly know Eagle (or electronics) have a look at it and let me know if I missed something ?

One handy feature of Eagle is defining "busses" - so you would not need to include 8 individual lines for the data bus in your circuit.
