:::::::
Several different memory expansion boards all cause the same problem:
:::::::
Streaks and missing bits start to show up on the screen. Sometimes entire
objects like the resize and front/back gadgets become corrupted on all
windows.  It would seem that these boards, all which have their own
memory controllers, are affecting CHIP memory.
:::::::
The esiest way to crash these defective expansion products is to bring up
a 'clock' window or two and let it sit for a few hours. The clock display
will trash and eventually crash with an address error or illegal
instruction trap.
:::::::
What in the design of these boards is defective?  Would any designer that
has solved or avoided this problem like to comment on the technical
aspects?
