I'm glad that it worked, this will certainly make further diagnostics
easier, and you have a usable machine anyway.

First: to double-check, how did you know it was a NVRAM failure, did LEDs
show DC (xxox xxoo)?
Second: it may also be that DROM itself is faulty, a bit may have flipped
for example; NB this is UV EPROM, so things happen. Maybe someone can
share a known-good image.
You are welcome!
