[rescue] memory in a classic

[Joshua D Boyd]

I'm trying to upgrade the ram in a sparc classic.

So, there are 6 simm sockets.  I think I have to add simms in pairs, right?
So, which is the first bank the bank nearest the front, or the bank nearest the
back?  

I have 4 parity 16megs simms that I'm trying to put in this machine, plus 2
4 meg simms.  The 4 megs were taken from the same machine yesterday.  The 16s
were taken in working condition from an IPX.  2 of these simms have sun part
numbers, the other 2 don't.

I've tried every pair in the front and the back slots, and still no luck 
getting the machine to survice to the openboot prompt.  Some of the errors
I've been getting are:
Data Access Exception

and

ERROR : FPU Exception Did Not Block Store, addr = 00600000, exp = 00000000, obs = 0f884010, xor = 0f884010
     U-NUMBER : Suspect Tsunami Module

and

     ERROR : FPU Registerfile Stuck-at Fault

         0000001e :  00000000  0f80fbbf
     U-NUMBER : Suspect Tsunami Module

Also, I have a pair of 8meg simms.  They have 24chips on them.  Would this 
indicate that they are parity?  I also have 2 16meg simms with only 8 chips,
so I'm thinking there is no chance they are parity.
