1-4 set the switches as shown to select FBMCPU
mode which allows 8 keyboard addresses
SW3 - Mode
This mode is to allow the BBUS/I-F to connect to the processor of our larger FBM matrix system. The FBM matrix
allows up to 8 keyboard positions where the standard TX1500 mode allows 4 addresses.
If the BBUS/I-F is used with a TX1500 then DO NOT use this mode.
