 ## 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.
