I'm pulling together my parts list for building the N8 HC and I have a few
confirmatory questions based on the schematic:
* What are the proper oscillator frequencies for the CPU and floppy chips? I
think it's 16MHz and 18.432MHz, respectively, but I wanted to confirm. The
part number for the CPU looks like a 33MHz part.
* What is the part number for the 9VDC coaxial power jack?
* What is the part number for the SD card slot? DigiKey has 10 different
ones from TE Electronics and Wurth. Also, is a push-pull or ejector type
preferred for this part?
* P45. This is for the SuperCap. Is there a part number for this cap?
Thanks!
