Local network

Greetings, All! Previously, Spectrum literature contained advertisements for educational computer complexes based on ZX, in which computers united into a multifunctional local network, with software support by N. Rodionov. I wonder what it's like did this network represent? [REAL ZX]

There was something similar in the Yamaha MSX (aka KUVT). I saw an option when all Spectrums (15 pieces) were in parallel connected via a tape port. In proprietary Interface-1 there were two ports, and all Spectrums were connected in series.
