   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
