Hello,
I read the Q22 specification (search "Q22 specification" on this page:
http://www.chd.dyndns.org/qbus_ide/ ) but the parity check function is still
not clear to me. My questions are,
1. Is there parity check when interrupt vector is read ?
2. Is there parity check if IO page is read?
3. What is the polarity of the parity bit?
Those questions are not answered from the specification. Any expert here?
Thanks
