At the time of Doom’s production, id Software was using a NeXTcube for its graphic engine development, so the NeXTSTEP version of Doom actually existed before the MS-DOS version and carries the name NeXTDoom. The application is sluggish on anything other than an Motorola 68040-based NeXTstation or NeXTcube (the more memory, the better), and has no sound support (DMX was not supported on NeXTSTEP). With OPENSTEP on the most recent i386 hardware, it runs smoothly under all conditions up to screen sizes of 400%. The released version is labeled v1.2, with programming credited to John Carmack, John Romero, and Dave Taylor.
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.
