SUCCESSFULLY TESTED ON:
............................... C128D (Plastic) with 64K expanded VDC-RAM
...... Commodore 1901, 1084 and GBS-8220 CGA-VGA-converter with Video-DAC
NOTE:
....................... Will *NOT* run on VICE (up to 2.3 at least, since
.............................these modes are not supported (yet) by VICE)
SHORT DESCRIPTION:
A slideshow of several video-modes for the C128 with 64K VDC
- 640x480 interlace 8x2 color resolution
- 640x576 interlace 8x3 color resolution
- 480x252 non-interlace 8x1 color resolution
- 640x400 non-interlace 8x2 color resolution
- 720x700 interlace monochrome
- two text modes with larger used screen area
This little demo shows some rare graphic modes on the VDC with some
converted images. Very colorfur pictures in resolutions of 640x480 or
640x576 are possible as well as high resolution of up to 720x700 pixels.
Also two text modes are included which provide a larger used screen area.
Converters and sources are included.
INSTRUCTIONS:
The demo consists of eight .d64-files. The first one is autobooting on
the C128 (or just run "vdc mode mania") to start the viewer. Please note
that not all modes will display on all monitors. They are sorted in
likeliness of display compatibility. VDC-IHFLI and VDC-ITFLI should work
on most devices, while VDC-HFLI and VDC-IMONO use very low vertical
frequencies for which you will most likely have to adjust the vertical
sync and vertical size on your monitor - if you have those controls.
The converters for the color graphics work on the PC and expect a .ppm
(Portable Pixel Map)-file to convert in exactly the right resolution
named 'input.ppm' - it then produces some files which can be read by the
appropriate -view BASIC-application on the C128.
The converter for the monochrome 720x700 mode is a simple BASIC 7-program
which expect a .pgm (Portable Graymap)-file. I suggest using this one
in VICE and warp-mode.
If you want to know more about those modes in general, please also have a
look at Commodore Free Magazine #55 at:
