“The Wave” is a Web Browser for GEOS (with the Wheels extension) on C64/C128 machines with a SuperCPU and a RAM extension.
A while ago, Maurice Randall, the author, published the source of the V1.0 version as a WR3 archive that contained the assembly source in GeoWrite format and some developer documentation.
I converted the files into plain text and published them at github.com/mist64/thewave.
