UNIX-pc memory problem

[Richard E. W. Moore]

I have a 512K expansion memory board which fails diagnostics with
the following message:

		TEST 3
		SUBTEST 1
		PASS 7
		NO PARITY INTERRUPT AT LOCATION 200008

Could this mean that a parity generator chip has gone bad?  If so,
how can I find its location on the board?  Any help would be
appreciated.
