A software development kit for MS-DOS programming #VintageComputing #MSDOS #SDK
The DOS_SDK is a software developer kit (SDK) for developing DOS software for x86 machines, including IBM PC compatibles and NEC PC-98
This SDK is modeled after the Amiga NDK (Native Development Kit). The Amiga NDK contains a set of header files and libraries for both assembly and C development, which provides all the required constants, flags, data structures and whatnot to interface directly with the hardware, and having readable code making use of human-readable symbols and type definitions.
An equivalent for the IBM PC platform, or PC DOS/MS-DOS/compatible environments has never been available to my knowledge. This SDK attempts to fill that void. Think of it as Ralfs Interrupt List and Bochs ports.lst turned into .inc/.asm and .h/.c files ready for use in a programming environment.
For system-specific or hardware/standard-specific definitions, a prefix is used for the symbols. For example, the IBM PC-specific symbols are prefixed with PC_, and NEC PC-98-specific symbols are prefixed with PC98_. For graphics standards, we can see MDA_, HERC_, CGA_, EGA_ and VGA_ prefixes.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
