MZ-80K Software Collection

Brief Overview

The MZ-80K was introduced in 1978 in Japan, and 1979 in the UK. It contains a Zylog Z80-compatible processor running at 2MHz. The screen is monochrome and has a resolution of 40x25 characters. Individual pixels cannot be controlled - preset characters must be used instead. Video memory is shared with system memory and read/writes must be manually synchronized with v-blanking to avoid a "snow" effect.

Other information can be found at original.sharpmz.org.

Tools Used


HopSkip

An arcade-style game where you must avoid solid blocks while jumping to collect objects flying across the screen. It uses fixed-point binary to control the acceleration, velocity, and position of the player for smooth movement despite the display limitations. The game has a high-score system which allows players to compete against each other and record their best performance.
