I have added a small memory chip to store about 1000 programs which will load similar to the Classic replacement board.

After a recent post I saw, I also added an option to override the write protect switch so you can re-write programs onto original cards if they have lost their programs.

Is this a bare board, or populated with all components so just drop-in to a '67 chassis?

This is well worth considering even for a working '67 to have that write card override feature and huge program space (continuous memory?). These 2 features address my most annoying limitations of a '67, so well done Tony, keep going!
