Two ways of programming - fit a preprogrammed
DIL, or fit an SO8 and program on board.
If a 5V programmer is used then the signals
should be passed through a small pcb inserted
into the programmer's zif socket. This pcb
would condition the signals to enable 3 volt
programming without damaging IC10.
