HP DIO and DIO-II bus devices
|
||||
|
||||
DIO is 16-bit, essentially the MC68000 bus
|
||||
DIO-II extends to 32-bit for 68020/030/040 machines
|
||||
|
||||
16-bit DIO cards fit and work in either 16 or 32 bit systems, much like 8-bit ISA.
|
||||
32-bit DIO-II cards only work in 32 bit DIO-II systems.
