Hi, I am interested in making a simple Z80 computer. I would like to use a CAD program, preferably one with autorouting, to design a PCB for it rather than use prototype boards. Eagle PCB CAD looks promising but I have no experience in using a PCB CAD program. As this is a hobby, I'd like to keep the costs less than $200. The hobbyist license costs $125 which would be ideal. http://www.cadsoftusa.com/ I tried Kicad but it did not work very well for me. I was able to layout the schematic but the PCB layout was very complex and many of the parts were not supported correctly. I was not able to get the autorouting feature to work well either. Has any one use the Eagle CAD program to make a simple SBC and can offer some advice on how to do make my own PCB for a Z80 SBC? I'd like to start small so here is the circuit I have selected: http://z80.info/gfx/z80test.gif Has anyone done this and would be willing to advise and/or work on a Z80 SBC project? Thanks! Andrew Lynch PS, I think this is "on topic" since Z80 SBCs are definitely "classic computers" like in NorthStar, KayPro, WaveMate, Zenith, Vector Graphic, etc.
