The data lines on the PLCC32 socket are reversed, so you can't flash a standard ROM image without reversing its byte order first.
This has been done because routing would have been a mess otherwise. When using the sockets instead of a SIMM close the two solder jumpers on the back near the ROMs at the marked position "V"
The other jumper settings are for experimental in system programming support (for which no software exists yet)

They're just test points in case someone is using a modern power supply replacement and might want to experiment with soft power.PFW - ADB.PWR
