Yes, I hear about the story, but not a detailed.
I don't understood the original Vega concept: it is a stupid Spectrum parody with few keys only... most important QAOP are also missing... at same time released the Recreated ZX Spectrum, which are looks good, but it is only a BT keyboard for a emulator program on phone... why not put the Vega board to a Recrated case?
Vega+ also not a Spectrum (for me), but least looks a good "kvarcjáték" (I don't know the right English word for these I think about Nintendo Game&Watch series, and their clones. These are very popular at middle of 80's in Hungary. I have a
Dragon Fighter), which is runs Spectrum games.
But hard to understood the lot of delays: just need to put the Vega to a new case, add battery and LCD, which are very popular components today...
