I have a C-Ltd SCSI controller and a Frances/Lucas
combo.  I have had problems running the HD above 12Mhz.  When
attempted, the harddisk will hang whenever it tries
to write.  I had previously been running at 20Mhz w/o HD
with no problems.  The hard drive just seems to have it's
speed limit.  

Modifications:

I have changed all of the logic on the SCSI to F and ACT
parts. (controller did not work at all with Lucas/Frances
without that change).  I am now trying to copy the PAL
to a faster GAL, but it seems to be secured from reading.

Does any Lucas/Frances owner have their C-Ltd controller
operating above 12Mhz?  Any recommendations?
