| <span style="color:#FF0000"><B>Beware !</B> Pinouts found elsewhere have ROMOE/4MB swapped, it's an error on the original schematics. ROMOE is on pin 33 bottom, 4MB is on pin 34 bottom.</span>

|
| possible correction (delete this text whenever): "SYSTEMB" appears to actually be a slot selection pin.
| | [[MV4]] |
| *On MV-2F, slot 1 A42 is connected to NEO-F0 SLOT0
| |
| *slot 2 A42 is connected to NEO-F0 SLOT1
| |
| Makes sense for 1F schematics to connect it straight to SYSTEMB since there are no other possible slots. On multislot, it comes from NEO-F0 (or equivalent) SLOT* outputs. NEO-F0 has SYSTEMB as an input so it probably only has SLOT* pins active when the cart ROMs are selected.
