i think that the "MacClip" newertech kits were pretty
cool because all the parts together and appear the
leads were presoldered, so really no soldering.

Or better still

i like these because you just move resistors. but you
need *two* soldering irons. note the 630 is there too.

it seems on my g3 though i just need to move a jumper.
boy, i should try this !

The 605 goes to 33 easily but you have to have the right clock for

i saw a chapter in a book on digital audio about dsp /
chips also recently. did you know they were array
processors ? the speedup is like whole multiples
of the processor speed and it is faster to start with.
i don't about the at&t ones in the macs, the book
discussed motorola dsps. all i have heard about the
at&t were they were harder to program. but this
is linux ...
