|
||||
- Pause (thanks a2geek)
|
||||
- ProDOS MLI calls tracing
|
||||
|
||||
By default the following configuration is launched:
|
||||
|
||||
- Enhanced Apple //e with 65c02 processor
|
||||
- RAMworks card with 80 column, RGB (with Video7 modes) and 8Gb RAM is aux slot
|
||||
- Memory Expansion card with 1Gb in slot 1
|
||||
- VidHD card (SHR support) in slot 2
|
||||
- FASTChip Accelerator card in slot 3
|
||||
- ThunderClock Plus card in slot 4
|
||||
- SmartPort card with 1 device in slot 5 (if an image is provided with -disk35)
|
||||
- DiskII controller card in slot 6
|
||||
- SmartPort card with 1 device in slot 7 (if an image is provided with -hd)
|
||||
|
||||
## Running the emulator
|
||||
|
||||
No installation required. [Download](https://github.com/ivanizag/apple2/releases) the single file executable `apple2xxx_xxx` for linux or Mac, SDL2 graphics or console. Build from source to get the latest features.
