Emulated Woz Machine
Introduction
Two years ago between christmas and new year I wrote a tiny and incomplete 6502 emulator and turned it into an original Apple 1 emulator. It was a fun and nostalgic project to work on. I grew up with the Apple II and never had a change to see an Apple 1 in action.
A few weeks ago I decided to pick this project up again. I am extremely motivated to turn this into a high quality emulator that supports the Apple 1, Replica 1, Apple ][+ and Apple IIe. Some of that work is really close to being finished, other work will take many months of spare time hacking.
Goals & Status
Here are some of the things I want to accomplish for each emulated machine:
CPU Emulator
6502 support65C02 supportTracing facility- Debugger
- Speed throttling
Apple 1
8K / 6502 / Classic ROM
Terminal based emulationClassic display emulation (SDL based)- Cassette interface
Replica 1
32K / 65C02 / KRUSADER ROM
Terminal based emulationClassic display emulation (SDL based)- Cassette interface
- CFFA1 Support
Apple ][+
48K / 6502
Basic Apple ][+ architecture implementation - In progressDisk II emulation - In progressDisplay Emulation - 40 Column modeDisplay Emulation - Low resolution graphicsApple Language CardJoystick Support- Audio Support
- Display Emulation - High resolution graphics - Mostly works.
Building the emulator
cd src
make
Running the emulator
From the command line:
./src/ewm two --color --drive1 disks/DOS33-SamplePrograms.dsk
