Cavern 10

A stripped down re-implementation of Caverns of Mars in 10 lines of Turbo Basic:   Cavern10.atr (PAL) Cavern10-NTSC.atr (NTSC, no sound or animation)   Source at github.   Unfortunately I wasn't able to include weapons or much game play, so it's way too minimalist to be a real contender. Consider it a demo of lz4 compression in Turbo Basic.

Atari Beaglebone Expansion

Ilmenit's RastaConverter is an image conversion tool for Atari 8-bit computers. I wrote RastaMovie to stitch RastaConverter images together to make movies. The movie frames have to be switched very quickly to achieve a frame rate of 25-30 frames per second. This rules out SIO or IDE interfaces as you need around 500 KB/s throughput. You have to have the frames in memory. But the largest memory expansion commonly available is only 1088K. That's only enough for around 64 frames and they have to be

Do-it-yourself A/V Cable for 800XL

Last year, I wanted to make an A/V cable for my PAL 800XL that would support S-Video, Composite and Audio. After doing some research I found out that the DIN connector on the back of the 800XL is the same as the one commonly used for MIDI. So I bought a 5 ft MIDI cable from Best Buy and an S-Video plug from Radio Shack. I cut an RCA cable in half. I then proceeded to splice all of these components together to form the Frankenstein A/V cable pictured here:     I wrote the following text
