Good point... you would think they would have opted to make the ISA slots a completely
separate board from the mainboard to save some coin... and then sell that with the
bridgeboard instead of including it with the motherboard. Those extra ISA slots take up a
tremendous amount of real estate.

That and probably because some 8-bit cards slopped into what later
became the spot for the 16-bit extension. That's why most ISA boards
still had 1-2 8-bit slots until very late in the game.
But C= was notoriously cheap, so I'm sure they jumped at the chance to
save a few pennies (and back when the A2000 was being designed, people
*did* still use 8-bit serial cards and such).

Now
it's time to solder the isa connectors to the 2000 motherboard.
It's the scary part for me. :-)
Does anyone know why the connectors were left off the board in the first
place? It seems kind of silly since they went to the effort to route the
signals and have the holes drilled.
