it's tough to reverse engineer this visually because traces can run underneath the pads! as long as they don't touch the plated via barrel, they're not connected. I'm glad I've got the netlist.

I've already created a schematic from that netlist. it helps understand how the card works. it pretty much just buffers the address and data lines to the cable, although it also has a state machine for adding wait states to slow down the ISA bus.
