I got back to playing with the machine for a little. After a combination
of precision "wedging stuff in the lock" and some additional plugging and
unplugging the serial cable in and out repeatidly, the machine suddenly
woke up, skipped the passwd prompting screen, and actually booted the OS!

The command line login (from CDE) tells me I've got version 4 of AIX.
Someone mentioned I can reset the root passwd by booting off install

Does the version of the install cd have to match exactly? (ie. 4.y won't
boot 4.x...)

Can/how can I tell exactly what version I have?

Once I get that far, can anyone hold my hand through making this boot off
a cd & then reseting the passwd?

Thanks in advance,
