Although it was designed for model railroad use, check out our web
site at www.oaktreesystems.com and look at the O-48 output card. It
has 48 outputs, each of which can perform a variety of functions. It
was designed to take a Microstamp 11 as a direct plug-in, but with
two wires and a $1.00 chip, you can attach a Stamp or BX-24 to it.
You can also run it from a PC if so desired.
