I am trying to bring up a S-100 system using the California Computer
Systems 2718 2 serial + two parallel I/O card as a console. I have both
an A and B revision, and have noticed what appears to be a timing
problem with the aforesaid board. When I read the status for SIO port A,
it resets the status flag, causing a real problem when it's supposed to
be waiting on it's keyboard scan loop. The practical effect is that when
you are doing something like using DUMP to dump a file, it won't
recognise a ^S, and thus scrolls until the end. Is there anybody out
there with suggestions/recommendations to fix this problem? I have tried
to get through to "technical support" at CCS in Sunnyvale for quite some
time, with no success.
I am also looking for a copy of a message published out here a while
ago, which dealt with a patch to the CCS 2422 floppy disk controller
making it more reliable in 8" <=> 5" operation. I am planning on
implementing a mixed system, and a resend of this message would be
greatly appreciated.
Thanks in advance,
Kevin Belles
