Since the beginning of the project (2006), the Hx C Floppy emulators was designed to be very versatile and to support a large variety of computers / keyboards / samplers / CNC machines at a low cost.
Thanks to its versability the Hx C Floppy Emulator supports most existing floppy formats.
To program this chip you can use Quartus II and an Altera compatible JTAG probe (The Byte Blaster for example).
The programmer software can be downloaded on the Altera website.
With this tool the LCD screen and the buttons are becoming optional / useless.
You can even remove the LCD screen to put the SD Hx C Floppy Emulator inside the Amiga/Atari/CPC computer without case modification.
- Variable bitrate, flakey bits and long tracks, custom tracks support (emulating of copy protected floppies). - "jumper free" Design : Device configuration on the software.
After some long minutes of preparation, we boot up the Atari ST with this floppy disk and then we realize that the floppy disk lost some sectors and is unusable...This chip is connected to a 32KB SRAM used as buffer and a FT245 from FTDI for the USB communication.The bitstream to use to program the CPLD is available here.Actually Atari ST, Amstrad CPC and Amiga versions of this tools are available.Here a video-demo of this tool: Note : Please go to the download section to get the latest version.For people like me who began the computing with computers as Atari ST or Amiga and still possessing one, we still use it time to time for some instant of nostalgias by viewing some demos and/or by playing some old video games.However these computers are based on 3"1/2 floppy disk, so it's necessary to prepare them from a PC.If you look for a device supporting IPF / STX please a have a look to the USB Hx C Floppy Emulator device) Data integrity security of the original system respected ! No direct usage of not secured IMG/IMA/”ISO” images or direct flash media bridging without CRC in floppy emulation mode !With this tool the host computer can access directly to the SDCard to select files images and change the SDCard Hx C Floppy Emulator settings.This often occurs because in a lot of cases, the floppy disk drive of the computer is damaged.Regarding Amiga floppy disks, it's impossible to create them from a PC because their format is totally incompatible with the PC controllers.
