miscellaneous
| interlaced color-resolutions on the Mega ST |
 |
about:
run from the autofolder this small gadget installs a tsr that takes ad-
vantage of the Mega ST's Blitter to double the vertical resolution in the
ST color-modes using a technique known as hardware feature on the
falcon (i.e. interlacing).
it works on the STE and the Mega STE, as well. however, there it does
not make much of a sense as for those machines a number of similar
utilities, that make use of the finescroll registers present on the STE-
shifter instead, already exist. so i recommend you to use this one on a
Mega ST only. the source is included.
requirements/specs.:
-Mega ST (Mega STE/STE)
-RGB monitor

| overclocking the TT's FPU |
 |
about:
this document describes a cheap upgrade that enables you to overclock
your TT's FPU without much of an effort (neither financial, nor craftly). it is
very save not involving any modification of your mainboard.
requirements/specs.:
-soldering iron and screwdriver
-an oscillator plus some short wires
-gives you 48Mhz or more

| CrY image viewer |
 |
about:
this little tool was finished in a hurry for alive #12. it's supposed to demonstrate
my idea of emulating a 16bpp CrY mode on the TT as known from Atari's Jaguar
using interlacing. standard 4-4-8 CrY images can be viewed with the attached
utility called "cryview.ttp".
large images will get resized to fit the emulated 320x240 pixel resolution and
gimmicks like antialiasing, gamma readjustion and a grayscale mode have been
included (take a look into the readme.txt on how to use them).
it comes along with my own tga2cry conversion tool, the viewer itself, a doc
describing the used techniques and the complete sourcecode.
requirements/specs.:
-TT030
-VGA monitor

| mandelbrot explorer |
 |
about:
as above this package has been made up in a hurry along with an article for
alive #12 so don't expect it to be free of bugs. the goal was to optimize the
mandelbrot iteration loop as much as possible for the 68030 resulting in a solution
without any multiplications.
the demonstration program let's you zoom into a rather high resolution version of
the fractal somewhat using your mouse. however, due to the fact this is a lookup
table based method the zooming range is a bit limited.technical documentation
and the complete sourcecode are included as usual.
requirements/specs.:
-Falcon/TT030
-RGB/VGA monitor
-CT60 compatible

| BiQ v1.0 (lightweight, lossy imagecodec) |
 |
about:
this is my attempt at a lossy image codec that should allow you to include
more textures, graphics and so on in your 4ktros or 96ktros etc. without being
forced to generate them.
the codec uses a simple haar wavelet tree decomposition and achieves compres-
sion rates of up to 1:80. v1.0 offers support for 8bpp grayscale, 8bpp paletted
and 24bpp truecolor images. support for a 16bpp RGB and a 16bpp CrY (jaguar)
mode are planned for a future release. seperate size optimized 68k decoders for
the various file types are included besides the conversion tool (tga<->biq), an
example program and the complete source code.
for further instrucions on using the package please refer to the readme.txt.
requirements/specs.:
-TT030/Falcon
-RGB/VGA monitor
-Fastram support
-CT60 compatible

| TT03 hires slideshow |
 |
about:
a little slideshow demonstrating an intelaced display mode with 1280x480 pixels,
32 colors per scanline on the TT030.
a 50Khz stereo sample is replayed in the background and a VU-meter is displayed
on the screen's bottom.
requirements:
-TT030, 4+4 Mb ram
-VGA monitor
