IF YOU HAVE A PROBLEM SETTING UP YOUR COMPUTER OR GETTING IT TO OPERATE PROPERLY. DO THIS:

Check ALL your connections:

  • Do they match the connections shown in the diagram below?
  • Are all power switches turned ON?It you’re using a TV set for your display, is the switch on the computer’ TV switch-box set to computer? Is the TV tuned to either Channel 3 or Channel 4?

  • Hi there!
    I’m a 77 year old ex-IT guy who built his first cp/m based Z-80 computer back in the day when you started with a card cage and then populated it with individual i/o, disk drive & memory cards. This was @1980. Over the years I’ve built and rebuild my home computer system numerous times.

    Recently I was clearing out my lower level and came across my son’s Commodore 128 which had been stored there since 2000 or so. Looks to be in great shape but was missing some cables for a/v and connecting to the color monitor which was also present. I’ve purchased and received the cables but could use a little hand holding to advise on startup procedures as I never used this system. Single 1541? Diskette drive is also available.

    Separate boxes included complete CP/M OS and manual + 8 or more games also complete.
    Any advice???
