Hello!
Sorry, can write only english (i am russian)
Gald to present you my own development - ZX Spectrum, based on AVR microcontrollers Atmel.
Device is fully compartable with all of ZX mashines.
Heare you can see:

Hope it will be intereresting for you. Please, comment heare. Answer you questions. To obtain device mail me.
Thank you !!!

Am I right to understand that it's not really a clone but an emulator written for AVR with extra hardware for I/O? If so - how accurate is the emulation (because previous attempts to do Spectrum on AVR failed miserably in this area)? One of the hard-core timings test would be to run some demos - preferably second part of Shock - if it runs ok then the job was really well done :)

Lisitsin:
You are right, device uses emulation as working conception.
Device passes tests like Zexall, AUMT, Testprog. Z80tests pass with MEMPTR test, but few tests like IN A,R and BIT(HL) fails. Timing tests is a question, cose test, for example, TIMING just stop.
Such demo programs, like Vibrate is working all right

Ok. I see on the project page it can run Spectrum 48/128 software - can you try running this: http://www.worldofspectrum.org/infoseekid.cgi?id=0007726 in 48 mode, then skip to second part and post some screenshot or short video. This is a real video-timings compatibility test you need to pass ;)

Heare it is:

But after pressing "Space" it goes to Basic, as at AVR ZX and Spectaculator
