Searching for MAI Basic Four Information/Docs?

gatkinso asks: "My first job after leaving college was programming on an MAI Basic Four minicomputer (an MPx 8000). Even then I could tell that this was a hideous platform - and that was in comparision to the VAX that my college was running! Fast forward 11 years... and I am faced with such a beast again. This time I am converting a small businesses MAI system to a Linux based solution as opposed to actually maintaining the system. My problem is this: how to get the data from the MAI system to the PC? The MAI system does support ethernet, but this particular system doesn't have a NIC (or for that matter a driver for the nonexistant card). I can set up a serial connection, but the fastest rate I can achieve is 9600 baud. Tape is a solution.... but were are talking about 9 - 10GB of data.... and this will require close to 100 tapes! So what I am looking for is information about MAI Basic Four systems - where can I get hardware and software for such a beast? Also, documentation would be nice (I have a fairly complete set of documentation already, but more is always welcome)."
