Apple II+ emulator
Portable emulator of an Apple II+. Written in Go.
Features
- Apple II+ with 48Kb of base RAM
- Sound
- 16 Sector diskettes in DSK format
- Emulated extension cards:
- DiskII controller
- 16Kb Language Card
- 256Kb Saturn RAM Card
- Graphic modes:
- Text, Lores and Hires
- Displays:
- Green monochrome monitor with half width pixel support
- NTSC Color TV (extracting the phase from the mono signal)
- ANSI Console, avoiding the SDL2 dependency
- Adjustable speed.
- Fast disk mode to set max speed while using the disks.
- Single file executable with embedded ROMs and DOS 3.3
Running the emulator
No installation required. Download the single file executable apple2xxx_xxx
for linux or Mac, SDL2 graphics or console.
Default mode
Execute without parameters to have an emulated Apple II+ with 64kb booting DOS 3.3 ready to run Applesoft:
casa@servidor:~$ ./apple2sdl
Play games
Download an DSK file (Asimov is an excellent source) and use the -disk
parameter.
casa@servidor:~$ ./apple2sdl -disk ~/Downloads/karateka.dsk
Terminal mode
To run text mode right on the terminal without the SDL2 dependency, use apple2console
. It runs on the console using ANSI escape codes. Input is sent to the emulated Apple II one line at a time:
casa@servidor:~$ ./apple2console
