32Kb or RAM, SD-card instant loading/saving plus additional AY-interface (well, the Japanese YM version, to be exact) in standard of classic ZX81's ZonX AY-interface from 80s.
There is also a ZX81's version of chipmusic SoundTracker.
I got the hardware from RWAP Software http://www.rwapsoftware.co.uk/zx812.html
