EduQuest TR Adapter
Looks just like an ISA version of the oh-so-common 16/4 adapter for MCA machines. Anyone ever seen the Ethernet adapter?
P1 (?) A jumper is present, over the rearmost set of pins.
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.
