|  Graphic 1 issue
I've just got a plus/4, and tried to programming on in basic, and found a strange issue.
In GRAPHIC 1 mode, the whole screen is black, and can't draw anything.
It happens with the simplest programs as well:
10 GRAPHIC 1,1
20 CIRCLE 1,160,100,30
Is may be a hardware issue? The games run correctly from tape.
Any idea?

This should not happen. You can try the GRAPHIC 2,1 mode: you will obtain a Hires screen with 5 text lines at bottom. Move the cursor down until you see the cursor and try input other commands.
Let me know

Seconded, this should not happen. Though you might want to try something like: COLOR 0, (2-15), 6 : COLOR 1, (2-15), 1 - before the GRAPHIC 1,1; basically set the background and ink to some color's brighter and darker version, just in case.

You can see, the program, and the result here:

If i set COLOR 0, and COLOR 1, ... than the result is visible, and the background is not black.

You can try this on any plus4 emulator or here, this should not happen.
This might be an issue with your ROM I guess.

I know, and I tried it on other emulators already.
But how can i fix this issue?
Is it possible to change the ROM?
