IBM PowerPC RS6000 860 - info needed

[Chris001]

To All,

I hope this is the right forum for this. I just became the owner of a IBM PowerPC RS6000 (circa 1996) running an AIX OS. Cosmetically it looking is great shape, no scratches or scuffs, possibly sat on someone's desk for its life. Powers up to the AIX login screen (I don't have the login). It passes all the built-in diags in the BIOS.

Any ideas on the worth of this laptop?
Any ideas on how to get into the AIX OS without the login?

Thanks,
Chris
