Single/Double Density Floppy-Disk Controller

Description\nThe uPD765A/B is an LSI floppy disk controller (FDC) chip which contains the circuitry and control functions for interfacing a processor to 4 floppy disk drives. It is capableof either IBM 3740 single density format (FM), or IBM System 34 double density format (MFM) including double-sid Address mark detection circuitry is internal to the FDC which simplifies the phase-locked loop and read electronics. The track stepping rate, head load time, and head unload time are user-programmable. The uPD765A/uPD765B offers additional features such as multi-track and multi-side read and write c;
