Alas, disklabels and file system layouts are very system-dependant.
You might have luck if the byte-order of both machines is the same.
For example, i was able to mount a UFS floppy created on an SVR4
machine under FreeBSD.  (SVR4 uses some 4.2BSD file system layout, i
think.)

If the byte order is different, you certainly don't stand a chance.

I dunno what NeXT uses as disk layout.
