Most E- Piano's of that period were based on Organ technology. It
probably has a master osc, and the square wave (probably) would then be
divided down. There would be basic waveform shaping for every key, and
that basically would be that.

I DOUBT IF YOU EVER MAKE IT ANY BETTER. That was the height of
technology then.
