Please help!  I'm trying to attach peripherals (A/D converters, analog
multiplexers) to the system bus socket of a Model 100.  I have a copy of
_Inside the Model 100_, which describes circuits for exclusively input
or output buffers/latches, but nothing bidirectional.  All my attempts
at hooking up a bidirectional buffer (using the read-not, write-not, and
chip-select lines) either get no results or latch up the machine.
Please reply if you've figured out how to do this, or if you'd like to
chat about ideas.
