To make a non-volatile software programmable DIP switch. Anyone? Like
those non-volatile digital potentiometers.
Thanks,

If its simply for setting options for a processor, the standard solution
is an eeprom.
If you want to actually use the paths through the switch as current
carriers to other devices, you need to implement that with a processor,
and still store the settings in the eeprom.
If there are still any parallel eproms around, you can just use one to
set the control lines of a cmos switch directly.
