Re: gEDA-user: Outsourcing PCB layout
Why not use RoHS chips? You can use those with leaded solder, as long
as they're not BGA or CSP.
Double-check the SRAM timing; 70ns seems too slow for a 25 MHz cpu.
Put two 0603's between circuit and chassis ground. For my furnace
controller, I populated these with a 10M resistor and a 0.1uF
capacitor.
