[comp.sys.cbm] GEOS and dual 1541s

brown@nicmad.UUCP (02/10/87)

I have a question for you Commodore Inc people.

There has been press in the past in regards to lockup problems when
using two 1541 drives on a C64.  Well, I thought that the problems
were part of my past, when I learned how to turn on the equipment
so that things wouldn't lock up.

But, along comes GEOS and it really aggrivates the Hell out of the
serial bus, to the point where things won't come up right, and the
buss will lock up when data is being transfered.

Has Commodore done any hardware patches for the old white case and
newer case (short board) 1541 drives or the C64 to help fix this
problem?

Also, I remember reading in this group that GEOS tends to show up
an error in the display chip.  Am I correct in this or not.  If so,
how do I know which chip it is, ie, date code, etc?  Also, where
can I get an up-to-date chip for my C64?

Any and all help with these problems would be appreciated by anyone,
especially Commodore people.

Thanks in advance.  My daughter also thanks you.
