Sun E250, NVRAM edit? (Serial Speeds, no console, etc)

Hello, I have an E250 Sun that belonged to a friend that passed away around 2008. It was colocated at a colocation office I had running in Virginia Beach. I pulled it out of storage, and would like to check if his public website is archived on it. Archive.org only has bits of it. Odds are low since it wasn't the main server, but worth a shot. I tried the usual Serial port A, but all I get is garbage. Tried all the common baud rates I could think of. If it's switched to diag mode, the diag stuff comes across in 9600bps. I tried the RSC port, it wants a password. Don't know it, didn't see anywhere online on how to reset it. I tried hooking up a console. Finally get the power brick in for the Samsung 770TFT LCD monitor I've held onto (it has 13w3.) At first it wasn't working. Tried both Type 5 and type 6 keyboards attached. No console. I found by removing the NVRAM, it will finally throw console. But no keyboard input. Stop-A, nothing. If I shove the NVRAM back in while it's running it immediatley goes black. Anyone know if the NVRAM strings are stored in plaintext in the NVRAM IC? If I were to dig out all the hardware that should be able to dump that chip is it something that is human readable / editable? I've done the coin cell hack on them before, but from memory the keyboard worked and it wasn't a big deal to do program in replacement MAC. But this is different, I need options removed. I'm thinking this thing has values in the NVRAM that are turning off the console and doing something funky to the serial baud rate. Or perhaps the baud rate in Solaris is set to something funky. - Ethan
