The 3G and 3GS are basically SPARCstation-5s in laptop form-factors,
if memory serves. Sun4m architecture. If yours predates those, it'll
be a SPARCstation-1/1+/2 processor, which is sun4c architecture. Both

Both NiCd and NiMH chemistries have nominal cell voltages of 1.2V.

What OS is it booting? A lot of what we do will be determined by
that. It's likely SunOS 4.x, probably 4.1.x. Please find out for sure.
Then...If you can get to an OpenBoot prompt, you can type "boot -s" to
boot into single-user mode. That should get you straight to a root
shell if it's running the earlier BSD-based SunOS 4.x. Let me know
when/if you can get that far, then I'll help you through getting rid of
the root password.
