An engineer named Jeff Keacher has connected his 27-year-old Macintosh Plus to the Internet. Keacher used a Raspberry Pi to do the heavy lifting, plus some serial adapters and voltage converters to connect it to the Macintosh’s serial port. 

Engineer Jeff Keacher says his first “real” computer was a Macintosh Plus. Now 27-years-old, the device has an 8 MHz processor, 4MB of RAM, and a 512×342 resolution 1-bit screen. Keacher decided he wanted to use it to surf the Web.
