[comp.sys.ridge] Need help with parity error.

howardr@hp-lsd.COS.HP.COM (Howard Rebel) (12/21/89)

Is any one still reading this group?

I aquired a ridge at our scrap sale.  
It is one of the units in the smaller cases,
not the larger ones about the size of a furnace.

It sort of works.

It falls into the debugger when I boot it.
Debugger complains about a parity error.
After several trips through the debugger to kill processes
that run into bad memory the thing will even run a select 
set of programs.  The bouncing balls program works great.

Can any one tell me how to map addresses given by the 
debugger to chips on the memory boards. 

I am not sure what model it is but will find out if there is
any one who may be able to help.

The system you have is a Ridge 32S ( a single users system).  I had one at my
desk for a month or two before it crashed.  Mine had the same symptoms yours
is having now.  I looked through all the documentation to find a solution.  It
recommended I insert a certain floppy to check the memory.  I was unable to
locate a copy of the floppy it requested.  Good luck!
