UNTESTED Rare Intellivision MUSIC SYNTHESIZER KEYBOARD for use with ECS

Description

Music Synthesizer
by
Mattel
for
Intellivision
The guys at Mattel/Intellivision got really ambitious, creating an Entertainment Computer System (ECS) as a computer add-on for the Intellivision console. And then this music synthesizer keyboard was an add-on for the ECS. And then you had to have the ONE game that was made for the synthesizer, Melody Blaster.
I for one, never got all the required pieces to play this keyboard. Therefore, I have never been able to test it. I've carried this keyboard across country through several moves, and now it's time to part with it. It will be shipped in a box I got from Amazon that just happens to fit it very nicely.
Please see the photos for the overall condition. There is definitely some wear/dirt shown in several of the close-ups. And one of the rubber pads is missing on one bottom corner.
This thing is oversized and weighs in at six pounds. So please be aware of the shipping cost when you bid.
