MEDDAC™ is the seeding point for designing a new approach to Operating System design itself. It is an Open Source project with roots in mainframe design and development started by the author in 1979. The Monitor Editor Disassembler Decompiler Assembler Compiler™ MEDDAC™ is the Open Source project for Generation 'N' [GENN™] Hardware design developed exclusively by the Author. MEDDAC™ Software is designed to accompany the BOSS™ Hardware. However, it must be stated that MEDDAC™ is also designed to run on any hardware that exists now and/or will exist in the future. This is accomplished the very unique design approach implemented in GenN™ hardware and software. Regardless of an hardware, MEDDAC™ will run on any system being the very first "truly" portable Operating System. The GENN™ Hardware. MEDDAC™ is a Compiler Operating System™[COS™] that includes its own Compiler in the Operating System itself. All modern Operating Systems include their Networking, as does MEDDAC™. Because of the distinction of including its own Compiler and Operating System, MEDDAC™ is first and foremost a COS™ and a full Network Compiler Operating System™, NCOS™ or COSN™.
