There is permanent activity on UD8 pin 20
UD8 has Pettester eprom and permanent activity on pin 20 also on UD9I am a little confused.
Are you telling me there is permanent activity on both UD8 AND UD9 pin 20?
Hang on a minute - have we still got the NOP generator in circuit?

I bought one of these as it was too cheap to bother making one myselfI used two 'tulip' sockets, with pins soldered together, and made a NOP Generator that way. The 6502 clearly plugs into the top one and the bottom has those pin headers with the right pin-width to go into the socket on the board. Even then, I plugged another duel-leaf socket into the one soldered into the motherboard to protect it.
The end result is this "Tower of Power"
