|  Textro as a genre
What do you guys think about textros? It would be really cool if we had some on the Plussy. The idea is to do effect on screen only using the built in C= charset. No raster tricks at all, so no modifying of any TED registers (except maybe FF14, to double buffer, and the color registers to init). I think it would be awesome if we held a compo.
The first part of Heartfixer is like that (almost) for example, although not very imaginative. It would be interesting to see vectors, plasmas, dycps, rasters, fire effects, etc using only the built in chars...

I am creating a GIF of text on the plus 4 but the pages I need to view I can't seem to access.
If I poke the high 5 of $ff14 / 65300 it seems to show ROM but I want to view ram color / screen data and page through.
Like below...
10 POKE 55,255:POKE 56,127
20 COLOR 0,1
30 COLOR 1,2
40 POKE 65300, PEEK(65300)OR(16*8)
50 POKE 65300, PEEK(65300)OR(17*8)
60 POKE 65300, PEEK(65300)OR(18*8)
70 GOTO 40
I tried a few variations of poke 65343,x but not sure if this is what I need or not.
Any guidance appreciated!

Hmm, I'm not sure why one would resurrect this 11 year-old thread... But doesn't matter.
So, setting $FF14 to above $80 will see the RAM/ROM depending on $FF3E/$FF3F. That sound kinda weird/redundant, so let me try to clarify. STA$FF3E means RAM is mapped from $8000. STA$FF3F means ROM is mapped from $8000. While you're running BASIC... You will need the ROM, since the BASIC is *in* the ROM. The interpreter itself will sometimes page in the RAM, when it needs to access it. (This is why you're seeing that "flashing" when you run the program, that's the interpreter paging RAM/ROM.)
In other words, "out of the box" this is not possible from BASIC.
I could suggest two approaches:
1) Just go with assembly, should be simple enough from what you're describing.
2) You could perhaps copy the ROM to RAM, and change some code, to allow BASIC to run while RAM is mapped all the time. (I think there are some programs that do this, for example the kind of stuff that changes BASIC error messages to another language, etc.) But that defeats the purpose, since you won't be able to store image data above $8000.
Hope this helps, let me know if you need more clarification.

Actually, it is an interesting topic (sorry, maybe I was not too active when started)
One comment: you are able to tell TED, where is the GFX memory, or the scren memory address, and will show it according to that.
It would be very weird, if the TED would create a screen from the ROM instead of the RAM content.
You can set these addresses from BASIC, with POKE command.
