The system is written in C and the executable file ranges from
110K to over 250K.  In principle it can be ported to any machine
with an adequate C compiler.  In fact, it is available on the PC,
Macintosh, NeXT, SPARC, Sun 3, 386/ix, MIPS, SGI, 3B1, RISC/6000,
Atari ST, and (thanks to Paul Chapman) the Archimedes; in the DEC
line of machines, J is currently only available on VAX/Ultrix or
VAX/BSD Unix.
 
Ports to VAX/VMS or to VM/CMS (or any EBCDIC-based system) would be
quite difficult.  (I know because I tried.)  Ports to machines with
less than 640K of main store would be probably be very difficult.
