FDC Emulator

The FDC emulator is a member of the SPS suite of preservation technologies.

Its job is to implement a definitive, low level, and most importantly accurate emulation for various brands of generic hardware floppy controllers. Almost of of these “off the shelf” controllers are derivatives of the NEC765A FDC.

The FDC emulator acts as a “plugin”, or “library” for emulators to allow inclusion of true floppy system emulation without needing to re-implement this complicated piece of functionality themselves.

The particular models of FDC currently supported are:
