"In a Product Change Notification (PCN) published on April 15, Zilog (now owned by Littelfuse) announced the End of Life for a range of Z80 products, specifically virtually all of the Z84C00 range. …"

"This started as a curiosity about operating systems and grew into a retro-styled homebrew computer made from modern microcontrollers."

"Click on the images for more info on the projects, this is a work in progress and will build on the pages as i go."

"PlasMa simulates a complete mini/mainframe system in a self-contained desktop-sized box containing real lights and switches. The system comprises a simulated 'mini-like' processor with a small amount of main memory, and simulated 'mainframe-like' peripherals such as a paper tape reader and punch, mag tapes, exchangeable disks and an operators console. The processor is 'micro-coded' and can run (currently) 3 different instruction sets; two based on the Princeton TOY architecture with 2K words memory for educational use, and a more advanced home-grown ISA based on NICE, with 64K words memory and floating point. The simulation runs on an ATmega2560 MCU which also controls the user-interface comprising approx 540 LEDs, 100 switches, 6 SD-cards, LCD screen, keypad, speaker, and interfaces for a PS/2 qwerty keyboard and MIDI."

"Intel is developing a new foundation for processors to try to keep up with exploding demand for new computing horsepower."
