How successful?

Not certain but the Pied Piper was not a popular model.

Comments

The monitor and stand pictured above were extras.
The Pied Piper Communicator was intended as a business computer and marketed as a 'portable'. However unlike the Osborne 1 and Osborne Executive portables, the Pied Piper lacked a built-in display and second disk drive. It also needed mains power so it was more of a 'movable' than a self-contained portable.
By 1983 the IBM PC running DOS was beginning to replace CP/M business computers and the Pied Piper had little to distinguish it in a crowded marketplace.
