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.

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 40Mhz.
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 ... brian -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
