[rescue] SPARCclassic restoration

[Richard]

Quick update

OK so on a hunch replaced the NVRAM chip.

On power on, Pressing STOP-D to start power on self test. Serial console plugged into ttya.

The machine now gets through post past the below error and goes through to
....
NVRAM Access Test
TOD Registers Test
Then  identifies the memory in each bank

and then powers off....!? Might have more work to do on the power supply.
