  • Hi,

     

    I have posted over in episode ONE and getting similar issues.

     

    I got the KIT3 made and having the same issues, I am trying to work out whether it is a SRAM issue for the ULA as when I remove the SRAM completely I get the normal vertical black lines which relate to bad lower RAM, on the 48K spectrum.

     

    Thanks

     

    Mike

    I've noticed in the board file that there are a few unrouted air wires.

  • Hello Ben,

    I was interested in recreating this project from the beginning.

    Now I'm 100 percent done with the build  but I'm having a problem like in this attachment.

    Do you have any idea what can cause this problem?

     

    Thanks.

    i think it is in the list of parts not sold

  • Hi Guys

    In the beginning I'm sorry for my bad english(I'm still learning). I know that episode was long time ago but I watched this episode of Ben Heck's show and I built this project. I bought PCB(zx_kit3) in Oshpark and soldered everything. Right now when I'm trying to connect LCD I'm receiving ULA screen full of garbage. Right now I'dont have any idea what went wrong. Was someone trying to build this or have any idea what to do?

  • Can I ask, where is the ULA (what part)?

  • in reply to monkeyman82

    All of the files we have are in the GitHub through the "Click Here" button.

  • I know this was along while ago but were the eagle files updated with parts/tracks missed by Ben?

  • As previously stated...just freakin awesome!!!

  • Thank you very much for sharing this video. I found it interesting and helpful.
