GEOS (Graphic Environment Operating System) version 2.0 from Berkeley Softworks for Commodore 64 and Commodore 128.
Today, there was a brief network outage in my house. I was troubleshooting the problem with the ISP's router. My 3⅚ year old child was helping me. He spotted a box nearby from #GEOS for #Commodore64 and asked, "is this the Internet?"
No. But it's close.
