  1. sad very sad. Oh well, scratching that one off the list. post picture of install, add a resistor or diode on wire to amp. It may lower threshold or provide some isolation. very odd.

     

    other choice fix Phi 2 with faster buffer chip like is done to almost all other pbi/noise/cart/bus issues

     

    What kind of diode should I wire?

  2. I couldn't see the traces in the picture to see what jumper pin would be used to toggle it. I wish he'd post more info on what he's selling. but at least you can get a distortion fix from my post.

     

    Connections I've made are correct for sure. I've connected covox to cpu pin39, too for check the difference. But distorted sound is only when pokey and covox outs are connected together to common amp input. It looks like covox signal is stronger than pokey. I've tried to put resistors on covox out but it doesn't helps.I'm not enough strong in electronic to know how to fix that.





  3. Instalation of this covox is very simple. :) in my opinion. It's socketed under PIA. I've no idea what goes wrong.


    I've another one problem. Maybe somebody could help me. I connected covox and pokey to one output and sound on amp is very distorted. Separately it's all ok.

    Now to play covox/pokey I must switch cable to two joints.

  4. Hi guys!

     

    I have instaled Ultimate, TKII stereo and Sophia. What can it be that I can't go in ultimate setup by help key? After power on, SpartaDOS is starting. I can go to BASIC by BASIC command. If I go out by BYE test ram is starting and HELP key (exit) doesn't work. WHy Help doesn't work? I've tried to connect 4 and 6 pins on keyboard matrix but it doesn't work. This happend after instal the Sophia upgrade.
