J80 is a Z80 emulator with a standard BIOS for a complete Microcomputer with working CP/M 2.2, CP/M 3.0, and one simple ZX Spectrum 48/128K emulator. The spectrum 128K version emulation is incomplete but working. The goal of this emulator is that the 'hardware' is built on-the-fly, reading the configuration from one file. This makes it very easy to add new peripherals or features.
