PROBLEM DESCRIPTION: When inserting a copy protected
application or game into the DuoDisk and starting up the
Apple II, II+, or IIe system, the disk fails to boot. The disk
may be damaged in the process.

CAUSE: If capacitors C29 and C30 are present on the
analog PCB, they can allow unintential writing to the disk. This
problem can be triggered by certain copy protection schemes.

CURE: Clip off the capacitors C29 and C30 at locations B1 and
A1 on the Duodisk Analog PCB.

If the above cure doesn't solve the problem, search on HTS and GTS
and the product name to obtain the general troubleshooting
procedure for the product.
