"n/a" Decoder info indicates these drivers get their signals as continuous
solenoids directly from the MPU at A4J4-5, 6, 7, and 8 and not the Decoder IC.

*NOTE*
The AS-2518-23 Lamp Driver Module does not use the CD4050 hex driver chips
so ignore that column if that's the style of lamp driver you have.


NOTES
I got all this information from the schematics and pretty much copied it verbatim.

If you notice any mistakes (I'm only human), please let me know and I'll fix it up.
