I've yet to pickup a greaseweasle, but do intend to one day, for now just using the old hardware, which is probably the root cause of the issues here for me.I am not familiar with that format
I know many people are using something called a greaseweasle for odd formats though and are having success. Neat little device that connects to a modern PC over USB.
Unfortunately I haven't been able to get mine work, but I think its an error between the chair and keyboard.
I am not sure which version of AIX mine came from. They are factory labeled by IBM for the 7012 line of RS6000s. I didn't personally make them.
