Introduction
Floppy disks have disappeared from the market many years ago, but surprisly the machines needed them still largely used in various domains :
Video games, Retro computing, Music, CNC machines (manufacturing/industrial process)... An alternative to the floppy disks is needed for these machines to solve the availabilty and reliabity issues brought by this old support.
I personnally started this project in 2006 to revive my Atari ST and Amiga machines and to make them easier to use in the incoming world without floppy disks and floppy drives.
The project have grown with the various support requests received during all these years. It now supports hundreds of machines and floppy formats. See the showroom to have a preview of the currently supported machines.
The HxC Floppy Emulator project main idea is to completely replace the floppy disk drive by an electronic device.
This electronic device emulate the floppy disk drive behavior and functionnalities.
The HxC Floppy emulators are designed to be very versatile and to support a large variety of computers / keyboards / samplers / CNC machines at a reasonable price.
The HxC Floppy Emulators support most existing floppy formats.
Today the HxC Floppy Emulator is a well established floppy disk drive replacement solution present into the retro-computing, Music and industrial domains. With several tens of thousands of units installed, the HxC Floppy Emulator is now a de facto reference !

USB HxC Floppy Emulator
USB HxC Floppy Emulator hardware main features
- Read only Floppy emulator (SD,DD,HD & ED mode)
( No Write Support ! Have a look to the SD Card version for the write support!)
- USB 1.1 device interface (based on the FTDI FT245.).
- MFM, FM and GCR compatible (can handle custom encoding).
- Bitrate between 63Kbits/s and 1MBits/s.(250 differents bitrates by step of 62.5ns).
- Variable bitrate, flakey bits and long tracks, custom tracks support (emulation of copy protected floppies).
- Can emulate floppies up to 128 tracks.
- "jumper free" design : Device configuration done by software.
- Flexible floppy interface: Shugart, IBM PC and Amiga compatible.
To see the list of computer tested with it, please go to this List
All necessary informations to build your own USB HxC Floppy Emulator are available here.
The main part of the USB HxC Floppy Emulator is a MAX EPM7128S CPLD from Altera with 128 Macrocell.
This chip is connected to a 32KB SRAM memory buffer and a FT245 from FTDI for the USB communication.

Warning : Do not disconnect the floppy ribbon while the USB is connected ! This may damage the emulator and your equipements.
Always disconnect the USB cable before connect/disconnect the floppy ribbon.

USB HxC Floppy Emulator's schematic
USB HxC Floppy Emulator CPLD
The bitstream to use to program the CPLD is available here.
To program this chip you can use Quartus II and an Altera compatible JTAG probe (The ByteBlaster for example).
The CPLD programming software can be downloaded from the Altera/Intel website.
Note : The EPM7128S CPLD can also be remplaced with the Atmel ATF1508AS.
the CPLD pinout assignation :
There are four LEDs on the board:
D1 : Power LED.
D2 : Select LED : Is on when the target computer acccess the floppy disk.
D3 : Step LED : Is on when the target computer is stepping/changing track.
D4 : Link LED : This is the USB link status: Is on when dialoging the host PC.
The VHDL sources are available here : VHDL USB HxC Floppy Emulator sources
How to build the USB HxC Floppy Emulator ?
There are two differents USB HxC Floppy Emulator PCBs :
- An "homebrew" version (Rev B). This is a one layer "Do It Yourself" PCB.
- A "Production" version (Rev C). This is a two layers PCB. I recommend this version since it have a better layout.
Regarding the features of the board there are no differences between these two boards.
You can downlead the Schematic / PCB Layout / BOM of the revision B & C board here !
If you don't want build it, this board is also available to purchase. Have a look to the sale points section.
