I tried it, and the compress'd files look like: $ od -x file.Z 0000000 1f9d 9067 c8bc 8153 c68d 8e04 08d9 a471 ... ^^^^ ^^ The magic # is the same, and the "bit-mode" is also the same... it just doesn't work on the UNIX PC/3B1. Also here's another entry ..

Because the Unix PC's file command sign-extends the numbers for some reason. I forgot to mention this in my previous posting, but you can see I had to discover it to do the "Ms.Dos file system" (I put "short 0xffffeb34").
