Released in 1982 this classic keyboard is in remarkable condition here's how they heralded it in 1982.....
It's possible to deduce the intended market for Hohner's new keyboard immediately from its name — the Family P100. This is another full-size keyboard from the prestigious manufacturers of the Pianet and Clavinet, this time with a full range of 8-note polyphonic voices and a selection of accompaniment features. While these latter are intended to aid the learner and home entertainer, it should be possible to use this keyboard for more diverse purposes as it would with the Casios of this world.

The overall appearance of the machine is good, the finish being in dark brown wood and plastic; there's a fitting for a music rest and for a stand. The keyboard is 4 octaves C-C, with a bank of square tabs in brown, white, grey and yellow above it on the sloping top panel. At the left a built-in speaker is provided, rated at 5W.

There are 12 instrumental voices, selected by six white pushbuttons towards the right hand end of the control panel, together with a single brown bank selector. The Vibraphone is particularly realistic, with a slow built-in tremolo, and the Wah Trumpet has a fast 'filter opening' effect with a high degree of resonance. Strings has a fixed delayed vibrato, and there's a good selection of other sounds including Piano, Harpsichord and Accordion. To the left of the voice pushbuttons and next to the power button are two buttons for Vibrato and for Sustain, both useful effects which give a reasonable degree of variation to the existing sounds.

There was a lot more but yo get the gist.
