Jumpers/Switches Not a clue,
but I'd suspect they are similar to or the same as the ISA TR adapters.
I should find out if this adapter supports RPL. It probably does...
seems that booting from a centralized server was pretty common in the
educational market so as to cut costs.
Looks just like an ISA version of the oh-so-common 16/4 adapter for
MCA machines. Anyone ever seen the Ethernet adapter?
