Cannot find Quartus 13 for Windows.
According to ADV2011, support for Cyclone III parts with Quartus Lite Edition versions 13.1.4 and 13.0 SP1 will remain available.
Any access to https://fpgasoftware.intel.com/?edition=lite with 13.anything jumps
to the Product Discontinuation Notice.
We need the software to support continuing projects using Cyclone III parts.
