    i have a manual flash microcontroller programmer.i need to enter in the
    program codes in binary throgh dip switch.i wanted to add a hex
    keyboard so that i do not need to enter the binary equivalents of the
    opcodes.can any body suggest me on how to do this

    What aniquated programming device is this??? What chip are you
    programming?

    Since you already have a working computer (in order to post here), get
    yourself a real programmer that connects to it.

  4. I remember doing that back in 1971 on a PDP11 copy that our company designed
    and built to control CNC lathes......12 bit op codes, diode matrix
    microcode, 16K ferrite store,120 ttl chip ALU,etc etc.
    Had to enter a boot loader that read in a punched tape that had the
    application program on it.... sweet memories .)

    Your school needs to seriously upgrade their equipment.

    The easiest way to do this may be to program a microcontroller to read
    the hex keypad, and use open collector buffers at the 16 output bits to
    simulate the DIP switches. ;-)

    Cheers
