In other words, fat chance. That's a Schlage lock, and non-trivial to pick, or even to break. You need the three-position switch, or a replacement, anyway. I have been successful at unscrewing the 3 thumbscrews at the back of the machine and *gently* levering the front edge of the "lid" up enough to clear the lock tab. Pretty easy to disassemble the barrel from there, and if you look carefully at the lock barrel itself, that brass strip running the length of the barrel holds the pins in. I've also resorted to a 3/8" carbide bit a couple of times when I was in a bad mood. That *always* works. Re the software, IBM released 4.3.2 and 4.3.3 for the price of the media for non-commercial use. It was damn nigh impossible to order it, but it was available. I did finally get a copy for $50, after ~18 hours on the phone with AIX Sales Group and the signing of a 17-page license contract that boiled down to "I realize I don't own nothing here and I'm not allowed to do nothing with it". In any case, IBM's unwritten rule concerning AIX is that the more folks there are who play with it, the more folks there will be who tell their boss to buy it. If it's not running in a business and you don't make a lot of noise about it, they won't send the BSA after you. I'm not sure, but I think v5.0 and v5.1 will run on that box, in a very leisurely fashion. v4.3.3 is your best bet. Doc
