I posted a while back about this problem.

I am wondering if I have a chance of reviving this system or if it is beyond
repair (by me)? I can't get anything out of the console port, and I don't
know if I should expect to be able to get output from there or not. If I
know that I should expect output on the serial port despite an NVRAM
self-test failure then I could investigate that further with my breakout box
(don't have a protocol analyser).

I have been unable to identify the NVRAM chips either.

Thanks for any help.
