HP 9122C Dual 1.44MB Floppy Drive

High Density 3.5" floppy drive using HP-IB interface to connect to HP computers. This drive uses HP's CS80 protocol for communicating with the computer.

Setup Notes
To get the most out of one of these with a Series 200 computer you will need a HP 98625 Disc Interface and HP 98620A DMA Controller which extend the system hardware to allow for faster access and booting from CS80 drives like this.
