Re: Tech: Lunar Lander, missing chips?

Lunar Lander also has the option for the program ROM's to exist in many smaller PROM's
instead of the larger Mask ROM's (24-pin). So if your big sockets are empty but if all
those smaller 16-pin sockets are populated, then your board is an earlier one with all the
PROM memory instead.
