This was done by gEDA on C8K with linux/HPPA :D :D :D

true, apparently stupid moves do happen which is why it's always a good idea not to rely on others when it comes to important things i.e. save the stuff that's important to you on your own

That happened to AIXPDSLIB. I've got some of it but not all of it, and almost none of the AIX 5 stuff. :/

Thanks. Creating packages on gEDA is simpler than on KiCAD, but the creating a decent preview involves a lot of interactions between the CAM processor (with a photoplotter and a drill machine in mind, gerber files) and imageMagic (gimp), plus a lot of manual operations passing data through a lot of python-scripts. E.g. holes are placed using the drilling-machine file, applying a dark circle filled with solid black, while all the gilding along the solder pad points is done by a gimp's filter which takes coordinates from one of the gerber files.

Next time I will just use "gerber view", even it the quality of the preview is not so good.

Creating a PCB is not an easy task and there are many ways for a fab house to mess it up. The above PCB is dual layers, without vias, it might be done at home but I am going to outsource the manufacture of all my PCBs, which is good since it saves your time, but you also need manufacturer's constraints. In this case the PCB is simple enough; I mean trace width and spacing are not critical so the might work without problems, but strictly speaking, the final result depends on the DFM (design for manufacture) rules and constraints.

I still have to find a way to include DFM within gEDA designs, so the C8K will be the perfect PCB-designer machine :D

VDU, using an fpga + SRAM

Re-done on C8K by a friend. It was a complex process, he said, the original design was done on a Windows/PC with DipTrace, then exported, and rendered on C8K. It's too complex and too time consuming. It's even more complex than the 3D-CAM process used by EagleCAD :roll:

Conclusion:
I assume the picture posted in the previous post (which was a planar 2D) is the best I can do on HPPA/linux with gEDA and ImageMagic
