I have a console, but not the main computer it's designed to connect to.
My goal is to interface this with a (Linux) PC, and hopefully more than just the keyboard. I have never tried something like this before.
So, given that I only have one half of the pair, how can I figure out what's what? How can I figure out what to send to it?
I know that it uses an RS-422 connection, but I know neither the data rate, the protocol, nor any commands. The probability of finding such technical data is very low, although I have access to user-level documentation (and I remember at least some of the operations from having used it back in the day).
I think I have a serial-to-usb converter, but that's probably for RS-232. I don't have (access to) an oscilloscope or signal analyzer, but I hope that some open source software exists...?
(Further details: I asked this over at Reverse Engineering, and it was suggested that you good folks may have tips.)
EDIT: By the way, these are the chassis: The Display chassis on top of the Comms chassis (neither of which I have, or plan to acquire).
