Thank you for this info. Characters wide 9px and larger is not only wasting bits - they can be used for some data. Look at - if W = 9 there are free 7-bits to store data without visible problem, similar way also larger W, but less free bits.

VDC 8563 was first used in Commodore 900 and there were 2 options: 1024x800 gfx or text console. Details about console I forgot, but I'll search in resources. BTW - 8563 version used in C900 had dedicated 128k RAM. Why was this cutted out I'll never understand, even how was 128k VDC RAM handled. In 64k is place (only data) max. for 1024x512. But nice will be to see 1024px text mode, if you try it. It was overload in very old thread. I'll find link and C900 details and post it here. Of course my posts are not important in compare of emulator developers.

So, I removed attributes and I think there's no repeating text. Text on screen is about W65C816 from Wikipedia. Mode needs last - adjust lines count to make it possible to display it on C1084 monitors, C1901 works. Of course - needs to change Editor.

Ok - please correct me if I'm writing wrong: Widest usable size is 9 pixels, larger is not applicable.

So, finally - is 9 and larger width by any way useful? No matter of hard work. 'Cause using 8x32 is useless while we are talking about non-interlace mode. Using 16x32 characters could be very useful...

Hi!
I want to try to use VDC text mode with characters 9x11. I know how to store data if is character height up to 16 pixels - this is by default.
We know that height is maximum 32 pixels - but how to store data when is character more than 16 pixels high? Or requires 32 pixels high character interlace?
Even - how to do it when is character more than 8 pixels wide? Here is also Q what with remaining bits - is possible to use them for custom data? Not affecting characters?
These Qs began when I tried to convert MS-DOS fonts with their standard size which are different to 8x8...
Thank you for explaining and maybe correction.

Yes - this effect I know, but I was leaving it as is 'cause I meant that it is problem of Editor - it supports 80x25 only... Now I know that it is not Editor - it is problem of mode...

Ok - I tried to understand. I created else one test: characters 33-127 and colors 1-16
Look below what I understand not.

Characters are repeater in loop from 1 to 0
