It's been ages since I saw there, but it was definitely graphics; maximum cable length was pretty limited; 12 feet or so. IIRC, the video signal itself was carried over three pairs of wires. Fourth pair of wires was used for bidirectional communications (keyboard, mouse, printer, DAC management). All the box did was generate the video timing signals, and feed the data through the DAC out to the monitor.

    It might be text only. There's a mention in InfoWorld 11/18/91: "Maxspeed
    corp. has introduced a controller to connect a 386 or 486 running a
    multiuser operating system to eight of the company's MaxStation base units.
    The $1,495 SH-8 MaxStation Controller is scheduled to ship at the end
    of this month." From that era it could simply be 80x25.
