Installed the JROK code and the DS1220 NVRAM chip on a Mr. Do's Castle for a forum member and ran into a problem...

The board wouldn't boot with the DS1220 installed. It would boot when probing the lower address pins with my logic probe... otherwise it would sit stuck in watchdog.

Installed a 9 pin 470 ohm SIP resistor pack on the first 8 address lines and tied the 9th pin to +5v and the board boots every time.

Just thought I'd pass that along if you run into troubles with installing that.
