[Coco] Program to detect a 6309 in a CoCo

[Juan Castro]

I remember seeing, in the list archives, a BASIC program that poked a small
machine language program to detect whether the CPU is a 6809 or a 6309. The
person who posted said it was a fix of a previous program that always said
6309 even if a 6809 was present.

And I can't find that message anymore! Yes I did try to google it, with
many many variants. Help?
