Fatal Error 0911

[fl332@cleveland.Freenet.Edu (John L. Graham)]

Ack! I picked up a 9/16 Zip and a flea market that looks like it's
been upgraded to a 9/64 (according to the Zip CDA) and all seems
well, except....I'm frequently getting a Fatal Error 0911 when I
quit back to the finder, launch some applications, or quit from
a program compiled with Orca Pascal. I can't find an error 0911
in any of my references. The only cure is to do a cold boot.
Any ideas on what this is? Should I degrade my Zip back to a
9/16? If soo, are all four of the original chips the same? they
look like two pairs, if so where do they go? i.e., can I blow
the Zip putting the original chips back in the wrong order.

Thanks o'plenty!
