    Help you find it? Install it?


    EPROM File Names: H546U5.hex ROM0(U5) (Checksum=B8AF) H546U6.hex ROM1(U6) (Checksum=F541)
    Equivalent ROM Type: HITACHI Type: 27C4001

    Install ROMs on Flash ROM Board (Part # A1939351), then connect board to Copy Tool (Part # A1939353). ROM0(U5) USES SLOT U5 AND ROM1(U6) USES SLOT U6 OF FLASH ROM BOARD.


    Since this model is from 99 its getting to be an old lady. I've only flashed machines that use PCMCIA or SDCards. That sounds like a ROM Programmer. But other than that. I'm of no help.

        Why do you want to upgrade the firmware on such an old machine. I found one on the Tessa-Support.com website. Hope this helps.

            Man do I know that. I've got analog copiers from 1992 in the field.
