I have been having a problem ever since I got my C128 with a 1571 drive to
replace my aging 64.  The problem is that when I hook up both drives and
the printer to either the 64 or the 128, I cannot use the printer, or the
drive at address 9.  

I have hardware changed the 1541 to be at address 9.  

The printer is a Sekosha C100 (1525 compaitble I believe) and works as a
1525 with GEOS.

Either both disk drives, or either disk drive and the printer will work
as long as one disk or the printer is powered off/disconnected.  This is
true with GEOS or in a normal mode of operation.

Is this a normal situation or is this unusual?  Does anyone else have this
problem?  Any help would be appreciated.

NOTE:  The 1571 and C128 are a couple of years old, in case this is relevant
at all.

Thanks in advance for any help.
