Here's a random music program ..

B 1 6 4 E B F 0 0
RESET, 1, RUN

This same thing was released in a different form in the early '80s in Japan: FX MYCON R-165.
There is a new unit which came out in July 09 in Japan: Gakken GMC-4. (http://www.retrothing.com/2009/07/new-gakken-4bit-micro-computer-kit.html)

The Gakken GMC-4 (http://www.retrothing.com/2009/07/new-gakken-4bit-micro-computer-kit.html) is almost the same as the Science Fair Microcomputer Trainer.

Only difference I see is the new Gakken GMC-4 unit can display a heart when waved .. and displays a numeric digit when playing the SIMON sound memory game. The included manual is only in Japanese .. but the MCT manual is online below.

There are several youtube videos of the GMC-4 in action.

Yup, I have one and think it's great. Haven't used it much lately, but someone contacted me about a hack he did with it:

I still have the MCT that my dad bought me when I was a kid. Amazingly, I even managed to keep up with the box and the manual. I was showing it to my gf a while back (until she met me, she didn't know that computers were capable of anything other than chat rooms) and she played played with it all night until the batteries went dead.

I remember taking the manual to school with me, and from behind a textbook during class, while the teacher was teaching the other kids history or spelling or what have you, I would be sitting there writing computer programs to try on the thing when I got home. My favorite was a model rocket countdown timer that I used to, well... launch model rockets!

I still have the folder that I kept all of those programs in somewhere...
