Modern Computer Corp NP-933

The NP-933 is a generic/ODM 386 notebook that was released in 1992. Modern Computer sold these under the NoteStar name. They owned the trademark for NoteStar, so it was a brand of theirs rather than another company that sold them. They may have also been sold under the Walkom name, another MCC trademark.

It appears that the two batteries in this laptop can be replaced with expansion devices of some kind. One port is labelled "EXT. DISK/RS-232" and the other is just labelled as an expansion bus.
