ZX circuit

Greetings, All! There is a diagram of the ZX-128, what model it is is unknown, I drew it from a computer board, on the board there is an inscription - 11KEEN93, all the signals were named after Skorpovsky, and the numbers microcircuits too ;) If anyone is interested, I can throw it in the echo. All the best, All! Best wishes *** Sergey ***! >>
