    Display upgraded - how can I use my old one?

    I had a go at this, and its really pretty easy!

    First, construct a parallel printer-port/display cable.
    I chopped the Centronics end off an old printer cable, and buzzed it
    out, the male 25way end will plug into the PC printer port. For the
    display end, I chopped an old disk drive plug, and soldered to it. A
    regulated +5 vdc supply (important!) goes to display pin 2, jumper
    display pins 1,3,&5 together, this is GND. A blob of silicon keeps it
    all stable.

    25way Display Use
    --------- --------- -----
    25 1 Gnd
    2 +5vdc
    3 Contrast (gnd this for max contrast)
    16 4 Register Select
    5 Read/Write (we only write, so gnd this too)
    1 6 Enable
    2 7 D0
    3 8 D1
    4 9 D2
    5 10 D3
    6 11 D4
    7 12 D5
    8 13 D6
    9 14 D7

    The display data sheet can be found here:

    Then find some software. For windows systems, I found and installed,
    port95nt.exe and lcdcenter03.zip. In no time my old display was showing
    all kinds of interesting stuff! Google lists lots of other similar
    programs, but I haven't tried any of them.

    Good luck!

    This software also works with noritake U-series VFD's... for windows users.
    http://backupteam.gamepoint.net/smartie/

    The VFD photos on this site are actually my shots of VFD's I used to
    own, which I submitted to the author awhile back (since he had no
    shots of anyone using VFD's).
