I, Terry A. Davis, wrote all 119,237 lines of TempleOS over the past 13.4 years (full-time). It can run on some bare metal 64-bit PC's from about 2005-2010 with no layering, libraries, tools, modules or anything from other sources. Otherwise, you run it in a virtual machine, like VMware, QEMU or VirtualBox. It is independent and stands alone. It has no networking, so it certainly doesn't call home. 100% of the src code is including on all distro's, from the kernel to the compiler to the boot loaders! It is public domain, not GPL. *) ::/Kernel/FontStd.HC, is taken from FreeDOS. It's public domain. *) ::/Kernel/FontCyrillic.HC, is taken from OrientDisplay without permission. *) ATA Reg and Cmd Definitions are originally from Linux. Later, I got the spec. *) The heap algorithm, ::/Kernel/Mem/MAllocFree.HC, is adapted from one I saw at Ticketmaster when I worked on their VAX operating system. *) The LZW compression algorithm, ::/Kernel/Compress.HC, came from a magazine and I implemented it when I worked for Ticketmaster. *) The adaptive-step-size-Runge-Kutta algorithm, ::/Adam/AMathODE.HC, is adapted from the book, Numeric Recipies in C. *) The mountain in some games is from The wolf in BlackDiamond is also from there. I took watermarked photos and converted to 16 color. *) The FAT32 file system is owned by MicroSoft. *) A few features were inspired by MATLAB, such as ans in expressions at the command-line. There is a lot of MSDOS , Windows, VAXTMOS (VAX Ticketmaster O.S.) and Unix inspiration, too, such as drive letters, command names, etc. *) I included PCIDevice Lst File. *) Thanks to whoever wrote this CppHtml.HC.Z. I'm a novice on web stuff and you helped me with html. See ::/Demo/ToHtmlToTXTDemo/ToHtml.HC. *) I used MagicISO to burn test CD's to help me understand the ISO9660 file system format. I mostly used the ISO9660 spec. *) I looked at bootable CD boot sects, but didn't learn anything, finding it easier to make my own. *) I think I got my original PC speaker code from Borland C. *) I found PS/2 keyboard and mouse code on the net and documentation. My code is very different. I found VGA reg info on the net. *) Thanks to for a couple tips. *) God told me to stick with 640x480 16 color and single-voice 8-bit signed MIDI-like sample for sound. He kept me from zombie-walking into making child windows like Windows. Instead, I made one window per task with no child windows. He also guided my progress, very obviously. *) I got Webster's Dictionary and The King James Bible from Project Gutenberg. *) John Carmack inspired me to use "Clamp" as a name instead of "Limit". He inspired me to use "needle" and "haystack" as names. He inspired me to simplify my Frames-Per-Second code. *) Bill Gates inspired me to add comments to my Help & Index. *) I hired an artist, Cody Rigby, for $3,000 worth of pixel art. *) Erik van der Karbargenbok wrote /Linux shell scripts -- GodPassage, GodWords. *) The random number generator is from Donald Knuth in the wikipedia entry for Linear_congruential_generator. * "MSDOS", "Windows", "MovieMaker", "MS Paint" and "FAT32" are trademarks owned by MicroSoft Corp. * "SiteBuilder" is a trademark owned by Yahoo!
