[SunRescue] 4/330 Problems

[Mark Yankee]

I'm having some problems with 2 Sun 4/330s that I just got.  The first one
has 8mb of ram and 2 5.25" FH hard drives with a P4 bus CG6 framebuffer.
The system starts up and the diag LEDs go through a few different steps but
stop at:

11010001

And if I boot the system up in diag mode the following is sent to serial port A:

  (9U expansion memory) SIMM in Error:   U1600  U1601  U1602  U1603 


This system doesn't have any memory expansion boards even though there are
memory expansion board errors.

The second system has a P4 bus CG6 framebuffer but doesn't have any ram or
hard drives in it and when started up it immediatelys stops with the diag
LEDs at:

11111111

If I start it up in diag mode nothing is sent to the serial port.  Does
anyone have any ideas?  Is it time to replace the NVRAMs?

Thanks,
