TOPIC



    There is a new version of LaserWriter NTX ROMs being rolled into production
    in late May. These ROMs contain an updated version of PostScript. PostScript
    version 51.8 allows for the following enhancements.

DISCUSSION


    - Full support of software switching between emulations and ports - It is
    now possible to both switch into and out of an emulation mode via software.

    - Improved support of multiple SCSI disks - Up to 8 SCSI hard disk drives can
    now be connected to the LaserWriter NTX SCSI port. Up to 80% of the hard
    disk with the lowest SCSI ID is used for font caching with the remainder of
    that disk and all of any other connected hard disk used for downloaded fonts.
    Each hard disk is now formatted as a separate volume which allows a user move
    a disk (other than the startup disk) between systems without needing to
    re-format.

    - Additional characters in the HP LaserJet+ emulation - Four characters have
    been added that had been left out of the original implementation of HP
    LaserJet+ emulation.

    - Improved default settings for HP LaserJet+ bit map printing - Previously,
    bitmaps in HP LaserJet+ mode were interpreted at 7-bit thus ignoring a
    significantbit. The new ROMs default to 8-bit serial communications.

    NOTE: These new ROMs are found in any LaserWriter NTX with a part number ending
    in 6004/A.
