Are you sure they're not referring to 8 bits of data and a parity bit? In any case, please give the address to the list so that it can be checked out.
www.altavista.digital.com, which is the address of almost everything :-) If you don't count the parity bit as part of the byte here, you probably shouldn't count it in a typical 7-bit-ASCII-plus-parity situation either. As far as jamming 9-bit-bytes across a bus, that almost certainly _is_ 8 bits of data and one parity bit; people have been agitating for and debating parity on memory busses for a long time. AT&T's Datakit switch (an ancestor of ATM) used 9-bit bytes on its data busses, where 8 bits were data-from-outside and one bit was a control-vs-data indicator, which let cards listening to the bus decide whether to think about the byte with their control processors or just shove them onto an output wire. # Thanks; Bill # Bill Stewart, stewarts@ix.netcom.com, +1-415-442-2215
