    These slots are called "Apple II Bus". Physically it is the same type of
slot connector as ISA, though 50-pins double-sided rather than 62-pins
(obviously the signal to each pin differ, it's not ISA compatible).

    It's an 8-bit slot that, I believe, is addressed at 1 MHz. They were 
used by the Apple II, II Plus, IIe, IIgs, Apple III and several Apple II
clones  and compatibles.
