This flash drive is to replace Hard drive in a Scorekeeper in an AMF Bowling Center with Boss Scoring System. The drive is ready to install with Boss 4.0 pre-installed. If you have a bad IDE HDD or just want to speed up boot time, this is the best replacement. Not only does it speed boot time, it also is not going to be damaged by the vibrations of the lanes like normal mechanical hard drives. If you need more than one, let me know, I can make multiple as needed.
