C) Learn how to do efficient PCB layout - utilize best practices. If its ugly, its probably not good, pointy 90 degree angles don't work well on a racetrack, they certainly don't work well on PCB's, unless transmitting RF is your thing - build a radio instead.
Um, at 3MHz, wiring shape is not much of an issue--even *length* is hardly an issue! Ground planes are rare. The only signal integrity consideration is long parallel runs of signals, and *that's* marginal. You must be accustomed to designing 100+MHz boards. ;-) -michael New, faster SUDOKU v2.0 solver for Apple II's!
