[Coco] PSG test code was Re: Sound/Speech Cart

[coco at jechar.ca]

I have downloaded the correct disk now and tested it on two systems.
1. A 2M 6309 coco3 with a mini-MPI
And
2. A 512K 6309 coco3 with a mini-MPI

Neither worked my results were as follows

DEMO.BAS
  writes LOADING SPEECH to the screen and nothing else happens ( I waited 
5 full minutes for some result. )
SCALESSF.BAS
   Crashes the coco with onscreen fireworks no sound.
SCALESSC.BAS  and SCALES12.BAS
   Screen goes Blank, no music, some low volume high pitched popping 
noises.

Have not tried it in emulator but I have Vcc somewhere so I will check 
that out.

If you have ideas about where these programs are crashing let me know 
what line number I could put a BREAK point at to confirm or debunk 
proper operation up to that point.

Hope I can be of help with testing.
