There's one called BEAV, based on an old version of MicroEMACS which
will display files in ASCII, decimal, hex, octal, EBCDIC and variations
on these. It's a bit old and crufty but it does the job. You can find it
in some Linux source archives, or in a comp.sources.misc archive (vol
26). The version I have is 1.32.
