okay ill see if this turns out better than my first post

i want to hack THIS mainframe becuase its part of the sofware company my dad works for, and i know everyone at the company and that they dont care if i hack it. I thought it would be a good place to learn.

No it has not been hacked before to my knowledge, and im guessing its because there are less than 100 people at the company and nothing of intrest on the machines

All i know about the architextre is that it is in front of the firewall

As for what ive read, its been every text file on hackers.com, along with others i just ran across. I also found a lot of clips from the book hacking exposed, but dont have the money to actullay buy it.
