    achtbit

    achtbit

    An 8 bit emulator created on the scratch, including an assembler.

    Ever had the experience of a 8 bit system, having max. 64k memory, using assembler to write effective small programs? This system is an experimental 8 bit, 16 color computer, with a processer similar to Z80, that (on my laptop using linux with NO opengl support) achieves up to 1.2 Million instructions per second and 50 Hz. screen refresh rate. It has a builtin assembler to load assembler programs. There is a rudimentary rom that implements some basic functions like line input, or a system clock. Also there is a snake game, (depending on that rom), as a reference and for fun! Take a look, give me your reply! When having ideas for better performance, let me know!
