PowSpot!

Tool for creation (in a PC) and display (in 8-bit Atari computers) of slides based presentations.

A minimum of 32kB of RAM is needed (~8kB for DOS, ~8kB for screen memory and display list, ~8kB for the read buffer and ~8kB for the PowSpot! executable).

Installation instructions.

Install luajit, lua-lgi and make packages.
Download, compile and install cc65, (you'd probable like to install it using checkinstall).
Download and compile AtariSIO tools from http://www.horus.com/~hias/atari/ even though only dir2atr is used.
Then you'll need a proper bootable DOS according to the disk type used; which is enhanced density by default. In the provided makefile, it is extracted from the dos2ed+2.5 template from atrcopy. You may install it using pip install atrcopy.
Once you've completed the previous steps, create a file named Images.mak defining the locations of DIR2ATR, ATRCOPY and in IMAGES the list of images used. Example:

DIR2ATR = atarisio-170702/tools/dir2atr
ATRCOPY = ~/.local/bin/atrcopy
IMAGES = \
  Page0057-6.png \
  Page0052-1.png \
  Page0052-2.png \
  Page0052-3.png

Finally run make and enjoy your new presentation at powspot.atr.

Usage instructions.

Create a lot of black and white 320x192 images.
List them in order in Images.mak.
Run make.

After compressed, each image takes about 2 ~ 3 KB. Meaning that you'll have space for about 40 ~ 50 slides in a 130KB enhanced density disk, or 55 ~ 80 slides in a double density one. You could use multiple floppy disks if you need to.
