SGM Test ROM?

I found the source code of the SGM test utility. Fortunately, I had a backup because my laptop hard drive crashed in 2014.

 

I made it to jump to the sound test code even if only a 1K Colecovision is found, also enabled the code for a walking piggy on the screen (I didn't enable it at the time because I was going to use it for a game, but never went to it)

 

When the music finishes it allows you to press the keys 1 to 6 in order to test each of the SN76489 channels, and the AY-3-8910 channels. cc @mytek

 

Also when the music finishes, you can move the pig using the stick.

Thanks for doing this I was finally able to test this on my ColecoVision and Adam.  It does bring up and interesting thing for me on the ColecoVision.   I am using a F18a (Clone using a Tang Nano) In both.   Different topic altogether I know. I've always thought that the Tang was making or something in the Coleco system run faster which leads to crashes in games like Donky Kong.  When playing the music it seems to be twice as fast in the Coleco then the Adam.   So strange but with this test I can clearly hear it.

Maybe it is refreshing the screen at double rate, or it needs a pull-up on the Interrupt pin.

Interesting may give that a try.

Just to clarify.   I'd putt something like a 4.7k resister between pins 12 and 16?
