   The F8 ROM is there, but it is missing both the D0 and D8 ROMs.  The D0, D8,
E0 and E8 ROMs are essential for a working II, plus the II's had a F8 ROM as
well.  The F0 spot was blank on a true II, the ][+ has all 6 sockets filled.

  The II has ROMs 341-0001, 0002, 0003, 0004 and 0016
  The ][+ has ROMs 341-0010, 0011, 0012, 0013, 0014, 0015 and 341-0020 (the
Autostart ROM)
