[Coco] speech pak question

[Bob Devries]

I know that the Tandy speech and sound pak needed to be modified to work on
a coco 3. I know that, 'cos I remember doing it a long, long, time a go (In
a galaxy far, far away).

Can someone remind me how this was done. I seem to remember two (or more)
ways. IIRC, I just changed the transistor to a 2N3906. Others may have other
ideas.

Comments please?
