I'd forgotten the whole story about MRCI and MRCI 2, DoubleSpace and
DriveSpace, and was under the mistaken impression everything was still
open, documented and (relatively) uncomplicated, until Neil Bradley
mentioned something in another posting.

So, you're right, we'd have to run the .BIN ... which is beginning to
sound a bit like work, unless we arrange to run other, better things
too.

Though, personally, I've never been attracted to the idea of FreeBSD
running DOS or Windows apps: I don't know how others feel about this.

Thanks for the input.
