[GreenKeys] Mystery stunt box?

[Nick England]

I have a stunt box configuration chart (don't remember where it came from)
that includes the following functions.
activate NO switch on NNNN
activate NO switch on FPK
activate NO switch on (FIGS-BLANK)Z
activate NO switch on (FIGS-BLANK)D
plus the usual other functions
Does this ring any UC-S with anyone?
Cheers,
