It has evolved into a program which is intended to be a thorough emulation of the Apple I computer. My emulator has a handful of specific milestones to achieve that will demonstrate its functionality: 1. Correctly interpret individual MOS 6502 instructions. 2. Run a system monitor program correctly. 3. Successfully run a BASIC program in Wozniak's BASIC interpreter. +4. Implement illegal instructions, and any other odditis of the 6502 present in the lifecycle of the Apple I. -There is potential to support illegal instructions in the future, but dealing with fringe cases is not a priority yet. +Planned features for the emulator include: +1. Two terminal emulators: one in ncurses, and another made with SDL to look like the original machine. +2. An emulation of the Apple cassette interface, which will be used to read in binary files as if they were on tape. -Planned core features for the emulator include: -1. A mode to run an SDL terminal emulator with the original Apple I font. -2. A mode to run within the users terminal. -3. A program to read binary files straight to memory.
