Hi guys.... I found in basement one functional ThinkPad Power Series 850 from my father, unfortunately he is forgotten username and password for operating system (AIX 4.14) :wall:.
if anyone has any idea how to get in?
You need boot in Manintanace Mode.
Thanks man! (I just saw that my CD reader on 850 series does not work. I hope that it will not be a problem)
