Graphics Programming
tri.prc 50613Jan 27, 2000 3D graphics demo for Palm OS featuring LaPlacian operators to do Z-buffer edge detection for display on low resolution B/W displays.
tri.zip 43685Mar 07, 2001 Source code for the above. See http://www.cryogenius.com/palm/ for more info.
fear.zip 348095Mar 30, 1999 Demo of a texture-mapped room. DOS4GW, Watcom C, DOS. Includes fixed point math routines, floor drawing, mapping a PCX file onto a wall, and so forth.
fearsrc.zip 33217Mar 30, 1999 C source code to the above
fearbsp.zip 219383Mar 30, 1999 Done with a BSP tree.

8086 Assembler
midicom.zip 46441Mar 30, 1999 MIDI protocol interpreter with a DOS text mode menuing system that I wrote to do MIDI Sysex backups of synthesizer patches. Supports Key Electronic's MIDIATOR and Sound Blaster compatible MIDI ports.
atman.zip 26971Mar 30, 1999 A simple character-mode arcade game that I wrote ages ago. Loosely based on Donkey Kong, it runs the same way on anything from a monochrome 4.77 Mhz XT to a 900 Mhz Thunderbird. It includes source examples of how to identify video cards, hook timer and keyboard interrupts, and deinstall handlers without crashing anything.

chop.zip 5050Mar 30, 1999 Chops a file up into floppy-sized pieces and CRCs them. Obviously, this is fairly old. Some things nowadays would take more floppies than a human could carry.
