    That's awesome! Think I might have to get one made up myself. Nice work

      I have a contact in the US who just picked up the following ECL chips for me that are needed for the project from an electronics surplus store in Silicon Valley...

      50 x 10124
      50 x 10125
      50 x 10116
      20 x 10105

      All NOS in original tubes.
      He'll look for the remaining ones and ECL RAM the next time he visits.

      I'm starting on laying out the tracks on the CPU PCB this weekend.

          I took a break from the PCB layout for a while but got some done today, a few hours were spent creating the solid silk layer footprints for components that aren't populated from factory (non-inverted video and audio amp). Started getting a few more tracks laid down but plan to spend the 5 day Christmas break working on it with the hope of completing it.
          Current progress...

              Some decent progress made over the last few days, over halfway done.

                Just a few more gaps to fill in and it's done, roughly 70 hours into it so far and still about 20-40 hours work left including routing about 50 more nets and checking for errors etc.
