Summary Regresssion 09435: zorba: Regression - black screen
Description Although marked not working it was at one time working pretty well, good display, able to boot a disk, and working keyboard.

Now it still boots and responds to the keyboard, but the screen is entirely black.

The crtc works with the z80dma, and this process no longer works.
Steps To Reproduce >mame zorba cpm

You don't need a disk to get a screen display - if it worked.

Looks like the problem occurred after 0.287, so we can't log reports until 0.288 comes out.

So this report is suspended until then.

I wanted to test all the other drivers that use the z80dma, before adding a comment, but ran out of time.

A comment has been added, Curt has responded, and he's looking into it.

Also updated the description to make it clear that the machine still works, it's only the screen that's gone faulty.
