This very simple modification makes the switch of the Slot 3.3 with the Slot 2:
- For the MSX Plus it is useful when you have kitplus installed.
- On the MSX DD-Plus it allows the internal drive interface to boot up before any external interface.
This inversion cause no issues or change any other behavior in the computers.
To proceed and apply the modification simply remove the wired-jumpers labeled as 25J108 and 25J109 and invert them (as demonstrated in the picture above).
Important: as you will have to cross the wires it is strongly recommended to use covered/protected wires, or make sure you isolate them to prevent short-circuit accidents.
That’s it. Your job is done!
