- Speccy2010 is FPGA development board built for the implementation of various gaming computers (but originally focused on ZX Spectrum and its clones).
- This project is next iteration of the firmware primarily aimed on implementation of various disk interfaces which was common in Central European region. DivMMC interface and objectively most advanced disk system MB-02 has been already implemeted in addition to build-it Betadisk interface.
- It brings you an improved File Manager which look like old good DOS commanders and let you to autoload snapshots, TAPs or disk images into the current machine configuration. Provides enhanced capabilities when the ESXDOS is loaded into DivMMC to autoload TAP and TRD files directly, without accessing NMI menu.
- It also includes a full-featured debugger built over the emulation core.
- More info how to control this Speccy2010 firmware you can find in wiki.

- Power supply 5V/1A
- Basic models and clones (including timing):
- ZX Spectrum 48k
- ZX Spectrum 128k
- Pentagon 128k/512k/1024k
