Pretty much anything I program it to do, with obvious exceptions. I've replaced both floppy drives with floppy emulators, installed a FreHD "hard drive", and use an esp8266 based wireless modem* for access to the outside world. Is the machine practical? In a modern context probably not, but I can read the news, get the weather, type up documents, manage household stuff, chat, etc, plus I just enjoy programming it. It's a refreshing break from the modern computers I use 8 hours a day during my job. Programming on my Macbook feels like work, even after hours, programming on the 4P feels more like hobby programming. *Some would say this is cheating, but I'm not of that mindset.
