The TPU has equivalent/superior functionality to the 67F687.  The '332
is more common than a 67F687 and cheaper too when you fold in all the
costs.  One could still tack a 67F687 onto a efi332 board.  As Andy V.
pointed out, the TPU is reprogrammable.  I've loaded different code into
it I got off of the Moto bbs.  They have a free assembler for it etc.
See early posting etc. for the rational.

I just ordered five from Hamilton Hallmark and two from a local 
disributor that I received today.  It's about as good as it's gonna
get.  They are CANADIAN $45.  I think this is a pretty good deal. YMMV.
Try ordering SPAKMC68332... if all else fails.  This is a special 2-pack.

The processor board is only a basic board. There might by a regulator 
on it but nothing fancy.  This is up to the 2nd board.
