I may try to
trace where the switches connect to to see which ones
are plausible guesses for what I want.
If it's anything like the BP1, those
switches are read in firmware by
the microcontroller. Unless you fancy disassembling the firmware,
you'll not make any sense of them.
I could pull the PROM and try disassembling it. But I'm not sure it's
that bad; based on what the switch banks are in physical proximity to,
I suspect at least one of them controls electronics directly rather
than simply being read by the CPU.
Well, only one way to find out...now where's that
screwdriver...(actually, it's more like, where's the tuit stack gone).
