Hello,

If anyone is interested in turning on options in the 850SX, here is some info.

There may be a different way to do it but I come from a hardware background so I dig into hardware instead of software.

I read the eeproms on the memory card and have located the option bits, reprogrammed and reinstalled the eeprom (in a socket) and it all works fine.

I will not post too much in case no one cares!

These controls are old and all but impossible to get support from the maker. Otherwise I would suggest going through proper channels for option upgrades.
