  • Hello

    In the shop it says:
    The Kerah can be made compatible with C128 by mounting

    additional "connections". What are these additional connections?
    Where can I buy them?


    Thanks

    Chris

  • For the C128D, it's just adding a DB25 connector which is available in almost any electronics parts store or online shop. If you want to connect a plain C128 keyboard, it's going to be a bit harder, as the pin spacing is exactly the same as a D-Sub connector, which is *very* unusual for pin headers. What I did for the deveopment version was to remove pins from the unsulator of a regular 0.1" pin header, plased them one by one in the C128 keyboard connector, then held that on the PCB and soldered it. You need to be very careful not to use too much solder, as the pins may get stuck in the connector forever :-)

  • Hello Jens,
    thanks for the fast answer. Sound complicaed for me, because

    of my "hardware"-knowledge.

    I hope to find time for this procet soon!

  • I did something similar, but I cut the pins, plastic and all, into individual pins, inserted them into the plug and into the PCB and then soldered them. Worked really well.

  • Hi Hans


    so have you connected the commodore 128 keyboard to the keyrah V3?


    have you soldered the pins on the keyrah to connect the c128 keyboard (not D)

    Right?


    works?

  • This is a rather old thread from before the Keyrah V3 release. However, the solder spots on the previous versions were similar, and you will be able to do the same thing on Keyrah V3. It's a proven method.

  • Vorrei sapere, se compro il keyrah v3 e collego una tastiera c128 con saldatura, funzioneranno tutti i tasti con l'emulatore VICE?, anche i tasti "speciali" che il c64 non ha?

    40/80 schermi

    aiuto

    Esc

    alt

    tastiera numerica


    ???

  • I connected my Commodore 128 keyboard to the Keyrah 3.0 via a 25pin connector, but some keys don't match... am I doing something wrong?

  • There is a Keyrah V3-specific keymap for VICE. Are you using that?


    For the numeric keypad, disable the "Allow keyset joysticks" setting in VICE. Please see page 19 of the full manual.

  • these are the keys that don't match:


    pressing pound corresponds to cursor down


    pressing up arrow corresponds to =


    pressing = corresponds to up arrow


    shift lock doesn't work


    the "grey" keys do not match


    the "white" cursor direction keys only work down and right, if pressed with shift they do not work up and left


    esc, tab, alt and caps lock if pressed they are equivalent to the function keys f1 f3, f5, f7 if pressed with shift f2,f4,f6,f8


    and the other gray keys also do not match......


    obviously on vice i have set the positional keyboard and on the keyrah the power button is positioned in the center

  • You'll have to select the keyrah v3 keymap that is provided with VICE, the default keymap does not work for C128

  • I have in the vice directory

    gtk3_pos.vkm

    gtk3_sym.vkm

    gtk3_sym_de.vkm

    gtk3_sym_fr.vkm

  • Ok, I found the GTK files for the Keyrah, but not all the keys work...

    Am I doing something wrong?

    is it possible to remap and upgrade the Kayrah for the C128?

    I specifically bought the Keyrah to use the Commodore 128 keyboard with the VICE emulator, but it doesn't work...

  • Please be more specific: Which key doesn't work?


    Does that same key work with a normal Windows program (not Vice)?


    Jens

  • good morning,

    now after reading the manual regarding the commodore128 keyboard and having done various tests by selecting the various vkm everything works.
