I've just been asked to redo an old project, customer information is as scant as ever and the previous designer is long since retired. They gave me their old files, none of which are much use to me except what I think are some relay wiring drawings done in either protel 98 or 99. I don't need to copy or modify them, just look at them as they might contain some gold information. Anyone know of a free viewer for these old protel.sch? I tried Altium Designer Viewer but that refuses to do anything remotely resembling being useful. A google search throws up some options but Im wary of downloading random crap.

EasyEDA is a cloud-based EDA tool suite which supports and working collaboratively. Tools from EasyEDA include circuit simulation using Spice, PCB design, electronic circuit design and now RS-274X (Gerber) and Excellon, all are free.

To use this viewer you need to upload your gerber files, in RS-274X format, in a zip file. EasyEDA’s gerber viewer allows zooming in/out the imported gerber files, choosing the color of PCB, exporting to image, enable/disable view of layers (files) of gerber, sharing the gerber online using the URL after uploading the files and showing some analysis data (Design for Manufacturing DFM) from gerber files like the number of layers, hole and track sizes, clearances and dimension of board. EasyEDA offers some tutorials/links to learn how to export gerber files for different EDA tools like:,,.
