I'm new here in this forum and until now I got a lot of information out of this forum to get my Apple 1 up and running. But I still have one litte problem that hassels me:
When turn on my Apple 1, only 10 rows of _@_ are shown on the screen, the rest is blank. When I do a clear-screen and a reset, eveything looks fine. I have swapped arrount the 74161 and also the 2504, but it makes no difference. Does anybody know what could be the problem? What part of the video-section is reponsible to fill the start-screen with _@_ ?
