# FujiNet ProDOS Clock Driver
|
||||
|
||||
[FujiNet](https://fujinet.online/) for Apple II provides a number of devices via SmartPort. Alongside four block and a network device it has a real time clock device.
|
||||
|
||||
This driver is an adaptation of the other drivers in https://github.com/a2stuff/prodos-drivers
