I have a MicroPDP 11/73 I'm trying to get running again; it has a single
M7551-AP memory board (1MB) which appears to have a stuck bit; the
startup memory test fails with:
Expected Data = 125252
Bad Data = 125253
Address = 01400010
Any ideas how to determine which RAM chip needs to be replaced based on
the failing address?
Thanks,
Josh
