Yes.  I'm sorry I wasn't more clear.  I _did_ mention the 32-bitness of
the target machine.

Right.  If all I wanted was four 64KB files that concatenated into the
original, I could use split.

  and of course, you need to know the
"endianness" of the machine
 where the dump was generated to see which file corresponds
 to which column-slice of the rom. 
Also true.  I'll be guessing because the ROM sockets are not numbered
on the board.  :-(   It's a VAXstation/MicroVAX 2000, if anyone happens
to know what the EPROM byte order is.

I got an EPROM splitter utility from Don Maslin (thanks, Don!)  It 
appears to be just what I was after.

Sorry for the confusion and wasted bandwidth.
