ATAboy is a user-friendly bridge that allows classic IDE (PATA) hard drives to be connected to a modern computer over USB as a standard USB Mass Storage device. 

While cheap, modern adapters usually only work with newer "LBA" type drives, ATAboy works all the way back to the earliest CHS only, PIO Mode 0, ATA disks. It will also work with newer LBA type IDE disks, but that's not really what it's designed for.  Performance will be SLOW.

ATAboy features an "Award BIOS inspired" user friendly UI for drive configuration and setup.

ATAboy is fully Open Source, hardware and firmware.
