    Model 1's screen output is too low

    Replacing Z5, Z6 and Z57 did the trick! Thanks for the help!

    Model 1's screen output is too low

    No worries. I did discover some really crappy bodge work involving Z57, which is part of the sync circuit. I just pulled Z5, Z6 and Z57 and put in sockets. Waiting for new chips to arrive. I am checking the analog now.

    Model 1's screen output is too low

    R44 appears to be a plain old 10k resistor. R22 appears to be adjustable and affects the vertical sync. However, turning it to the point that the prompt line appears on the screen the screen starts vertically scrolling.

    Model 1's screen output is too low

    I have attached a picture. The top row is the list of numbers and the prompt is off the bottom of the screen. This happens on both my LCD and an original Model 1 monitor.

    Model 1's screen output is too low

    The output starts about 2 or 3 inches down on the screen and the cursor is somewhere below the screen. I verified its the computer not the monitor, but does anyone have any pointers on where to start looking?
