To post a picture, you click

To post a picture, you click on "Media browser" after typing your post.

Choose (or drag) a file to upload, then select the display style. The default style is to show the image inline, but the browser can also generate a "preview" or "teaser" with a link.

Your screen looks like there is a problem with video generation, maybe with the character rom or the 74LS166. I'm not sure.

It is definitely not a problem with the character ROM. Most likely it's due to a problem with the memory.

That's not gibberish. It's

That's not gibberish. It's lores graphics. When you were getting the beep it meant that the CPU was functionng correctly (along with ROM, RAM, and a bunch of other stuff). I assume this is an Apple II or II+ (you didn't say).

 

Try reseating/replacing the 74LS259 at location F14 on the motherbaord. This usually causes this symptom. Once you get a TEXT display you may find other issues.
