Credits Terry A. Davis wrote all of TempleOS over a span of 15.0 years (full-time). ZealOS, written over a span of 3.2 years (part-time), is a fork of TempleOS. It can run on bare metal 64-bit PC's from about 2007-2019 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 can stand alone. 100% of the operating system source code is included on all distros, from the kernel to the compiler to the applications, including public-domain BIOS-mode boot loaders! It is public domain, not GPL. *) ATA Reg and Cmd Definitions are originally from Linux. Later, Terry got the spec. *) The heap algorithm, ::/Kernel/Memory/MAllocFree.ZC, is adapted from one Terry saw at Ticketmaster when he worked on their VAX operating system. *) The adaptive-step-size-Runge-Kutta algorithm, ::/System/MathODE.ZC, is adapted from the book, Numerical Recipes in C. *) The mountain in some games is from http://www.public-domain-photos.com. The wolf in BlackDiamond is also from there. Te rry 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. *) Terry included PCIDevice List File. *) Thanks to whoever wrote this CppHtml.ZC. Terry was a novice on web stuff and you helped him with html. See ::/Demo/ToHtmlToTXTDemo/ToHtml.ZC. *) Terry used the ISO9660 spec to help him understand the ISO9660 file system format. *) Terry looked at bootable CD boot sectors, but didn't learn anything, finding it easier to make his own. *) Terry thought he got his original PC speaker code from Borland C. *) Terry found PS/2 keyboard and mouse code on the net and documentation. His code is very different. He found VGA register info on the net. *) Thanks to http://www.osdev.org for a couple tips. *) Terry got Webster's Dictionary and The King James Bible from Project Gutenberg. *) John Carmack inspired Terry to use "Clamp" as a name instead of "Limit". He inspired Terry to use "needle" and "haystack" as names. He inspired Terry to simplify his Frames-Per-Second code. *) Bill Gates inspired Terry to add comments to the Help & Index. *) Terry hired an artist, Cody Rigby, for $3,000 worth of pixel art. *) The random number generator is from Donald Knuth in the wikipedia entry for Linear_congruential_generator. *) The optional UEFI-compatible Limine bootloader is copyrighted by GitHub user 'mintsuki' and project contributors, under the BSD-2 License. This bootloader is NOT included by default, and is only available on ZealOS distro ISO builds marked "BSD2-UEFI" in the ISO filename. * "MSDOS", "Windows", and "FAT32" are trademarks owned by MicroSoft Corp. * "MATLAB" is a trademark owned by The Math Works, Inc. * "QEMU" is a trademark owned by Fabrice Bellard. * "VAX" is a trademark owned by Digital Equipment Corp. * "Linux" is a trademark owned by Linus Torvalds. * "VAXTMOS" is a trademark owned by Ticketmaster.
