[comp.sys.m6809] CoCo 3 Disk Controller mysteries

ingoldsby@calgary.UUCP (01/28/87)

Has anyone out there experienced peculiar things with the CoCo 3 and old
disk controllers?  I am using an old R/S disk controller, the one that
used 12v (thanks R/S, penalize those of us who supported you from the
beginning) and I have added a 12v power supply to my CoCo 3.  It basically
works O.K., although I am having some flakiness problems.  For example,
when I turn the computer on, it comes up with the appropriate DISK BASIC
banner, but frequently the first disk access causes the computer to go off
into a world of its own.  Resetting the computer and trying again cures
the problem. 
 
If it is just some initialization problem with BASIC, I really don't care
since I spend most of my time in OS9.  If there is some other compatibility
problem, I'd like to find out.  Thanks for any info.
