+- 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

 ## 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.
