This Music-Star Prototype was manufactured in December 1987 by Texas Instruments in their Research & development Department.
The Main printed circuit board (Main-PCB) of the Music-Star Prototype looks despite the missing components familiar to us.

The "50C42 Emulator" PCB used with this Music-Star Prototype is centered around a Bond-Out TSE50C4X-1GB Voice Synthesis Processor (VSP) in a large ceramic PGA housing and a TMS27C128 EPROM with 16k Byes capacity for both program and voice data.
