I have recently updated my little VDC Mode Mania demo with another graphics-mode: 800x600 Interlace Monochromeincluding 4 demonstration-pictures. This mode will work best on a Commodore-1084 monitor, as you can squeeze the image horizontally as well as vertically. The mode should work on nearly all 80-column-display devices though, even if not the full picture is visible. Using a Commodore 1901 e.g. the left and right border will be cut off as this monitor can only display about 750-760 pixels width. Have fun trying the new version: DOWNLOAD |

Thanks for 2015 update! I will test on my hardware and report on your software...

My NTSC TV does not like 600+ rasters... I guess if my TV were PAL compatible it *might* work...
I'm really sad because I would love to see your work!
Well, I did watch your YouTube video... awesome!!!!!!! So how does the 'progressive download' work? I can easily imagine loading color and bitmap separate... but the 'bitmap' part seems to load with progressively finer resolution. PLEASE EXPLAIN!!
Pretty please 
Edit Your post says "monochrome" but the YouTube video is color... can you explain that too? Thanks!! /Edit

The progressive download looks that way because for interlace-mode you have TWO colormaps and TWO bitmaps to load. So 4 files per picture. I load each into memory and use a copy-memory-to-VDC-memory-routine for each file (which I "borrowed" from you - with your permission back in 2012 ;-))
Only the new 800x600 mode is monochrome. The YouTube shows all the modes of this Demo (640x480 interlace in 8x2 color resolution, 640x576 interlace in 8x3 colors, 480x252 non-interlace in 8x1 colors, 600x400 non-interlace in 8x2 colors, 720x700 monochrome and the new 800x600 monochrome). I suggest watching the YouTube in FullHD, you will be able to read the on-screen messages that way :-)
The 800x600 mode uses 644 total vertical lines (or 651 depending on how the VDC sees it, not really sure). That is just above PAL (625 lines) and may still work on some PAL-TVs.

Ah... 4 files per image... that makes sense! Glad my VDC-memory routines are helping the entire C128 community. Either way (600/644/651) my TV cries like a baby  But hopefully it works great with 1902/1084/compatible monitors! If anybody has a GBS-8220, please report! (With my S-Video adapter it fails, but I am not sure if the problem is the adapter or my NTSC-TV!)
Edit FYI, I am using a 'classic' CRT-type TV for now... I hope that an upgrade to 1080p TV might actually work... but so far I have not been impressed by modern devices' ability to render classic images, so I have not 'upgraded' ... *yet*... /Edit

It looked good on my Magnavox Professional. The 800 x 600 mono looked fine but rolled a bit. I think the 720 x700 monochrome may not have worked at all. I'll have to transfer all the images to the real hardware, I only did 4 or 5 to take a quick look.
