Faulty RAM on Apple IIc motherboard

[spec@vax2.concordia.ca (Mitchell Spector)]

   An Apple IIc (ROM 0) I bought the other day seems to have defective
DRAM chips on the motherboard. They're soldered-in of course, so I'd
like to know _exactly_ which chips need to be replaced. Conducting the
built-in self-test reports back the following:

     *RAM ZP 0 0 0 0 0 0 1 0 0

(I know the 1's are 'bad' chips, but which end would that be on and
what is the "ZP"? Which of the sixteen 8K DRAMs are at fault here?)
