[rescue] Sparc 20 Diag question

[rescue]

I have not found any further SS20 mainboards.

I have found at least some of my SS10/20 memory and cpu modules.  I 
need to go through what I have.

Sorry I've been slow on this, work was busy leading into the 
holidays.... and then.... the holidays :-)

Need to get through this stuff before work ramps back up again.
