Google is failing me on this one. A while back, I
picked up some
random boards on ePay. The boards all have the name TRIAD, and they
include a passive backplane, what appears to be a central controller
with an FPGA and a bunch of RAM, and several boards that each contain
two Z80s and ten 8530 serial communication chips. One of the oddest
things in the silk screening is the identification of two of the
ribbon connectors across the top of these latter boards: "LAMB/DROID,
ODD HALF" and "EVEN HALF". (Ironically, I just finished a really good
science fiction story regarding a sheep, entitled "The Android's
Dream"....)
Triad used to be very big in POS systems, particularly in the auto
parts business. Does that make any sense with your gizmo? Is that
an FPGA or just a custom gate array?
