NOTE: If you plan to design your own PC boards for options that you add to RB5X, we recommend you become very familiar with the mother board schematic contained later in this section so that you can make the appropriate pin assignments.


The mother board is fused for 1 amp.  The electronics that run the base unit draw about 1/4-amp; an RB5X with optional voice/sound synthesis and the BR Arm draws just over 1/2-amp. if you plan to install other options, you may want to use a larger fuse.


In addition to power and input/output (I/0) lines, sockets J1, J2, J3, and J4 on the mother board also have bus request, reset, disconnect, and clock lines available.  J5 has all of these lines plus address and data lines.
