PINOUTS
There are three instances of the Expansion Bus (so far), the original
A1000/ZORR0 specification, and the A2000 enhancement to this
original spec, and the B2000 (A2000-CR) specification. The ZORRO
specification is treated as a single instance for the purposes of this
chart, even though there are several different ZORRO bus
implementations from several different hardware manufacturers.
