Current features are: * Atari ST * Complete Atari ST chipset + * ST or STE configurable * Cycle exact 8 MHz 68000 CPU - * 4MB RAM - * PAL and NTSC color video via HDMI - * YM2149 sound via HDMI + * 4MB RAM, optional 8MB STRAM + * color and monochrome video via HDMI + * YM2149 and STE DMA sound via HDMI * Blitter * Supports most TOS * Tested with german TOS 1.04, german TOS 2.06 and US TOS 1.00 - * Mouse via IO pins of Tang Nano - * Full IKBD implementation - * Single floppy disk image stored on regular FAT formatted SD card - * Tested with 16 GB cards only + * Full IKBD implementation + * Mouse via IO pins of Tang Nano + * Joystick via IO pins of Tang Nano + * Floppy disk image stored on regular FAT formatted SD card + * Tested with several 4, 16 an d 32 GB cards + * Up to 32 .ST disk images selectable via on-screen-display ## Missing features * Support for keyboards - * Support for monochrome video - * Support for multiple ST floppy disk images stored on FAT formatted SD cards - * User interface (OSD) - * Full STE chipset support - * Support for 8 MBytes RAM as available on the Tang Nano 20k + * Support for floppy drive B + * Support for hard disk images * Floppy disk write support -Currently the FPGA on the Tang Nano 20k is already 70% full. It may thus -not be possible to add all missing features. +Currently the FPGA on the Tang Nano 20k is around 87% full and this setup +is considered to be mostly complete with respect to the FPGA itself. +Further development will focus on the BL616 microcontroller of the Tang +Nano 20k which will allow to implement the missing features. ## Getting started
