I /think/ the original 3100/20 used a proprietary 26-pin interface and
the 3100e/20 used something more like standard IDE.  There definitely is
more than one version.  I recall a 44-pin interface which was IDE plus
power, but not sure if that's what's in the 3100e.  It should be fairly
easy to check with a VOM, though.
