I (briefly) had to write code to run on GeoWorks GEOS. The code was written in a dialect of C with object oriented features that was compiled from .goc and .goh files to .c files in a manner similar to cfront. It was not a pleasant experience.
Edit: This was in 1997. We were writing a web browser for the Brother Geobook which was a device with late 90s PDA capabilities in the form factor of a late 90s laptop. I don't think that it was a particularly successful product.
