	Commodore DOES make that model, or almost exactly that
model. It is 1MB chip and 4MB fast. In fact, Commodore doesn't
make the model you bought, so I don't know what your dealer sold
you. That configuration hasn't existed since about October of
last year.

	It shouldn't do this. Call the 800 number and get your
on-site service.

	As before, it shouldn't do this.

	It isn't necessary for you to back up the system
partitions. You should have gotten disks with the computer (in
the thick binder called Using The System Software) which have the
OS on them, as well as an install program that'll copy the files
for you.
