That looks good - it would be worth starting a thread under Spectrum -> Hardware to maybe explain a bit more about this and what makes it different from the other Spectrum clones :D

Basically it is a Harlequin 48 with replace all digital ICs by 1 CPLD (EPM7128S), PCB is in ZX81 form factor.
It can do the same thing as Haelequin 48 but much cheaper.

The CPLD (EPM7128SLC84) is hard to find in Europe for a reasonable price.
I think that's why I never used it.
Can get one for around 30 EUR but EOL product as well.
