You mean the bus with, that is not the same as the bandwith?
Perhaps he means that the /23 uses only 18 bit. The first (low end) QBus
implementations used only 18 bits for address space. The QD32 can use
all 22 bits of a "full blown" QBus. AFAIK you can jumper the QD32 to use
only 18 bit adressing. Sorry I have my QD32/33 manual not at my hands...
