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 !

- A SD Card version emulating floppy disks from files images stored on a SD Card. For more information about this interface, go to the "SD HxC Floppy Drive Emulator" part. |
|
- A USB version which allows to connect the machine floppy disk drive interface to a PC with a USB cable. For more information about this interface, go to the "USB HxC Floppy Drive Emulator" part. |

Exploring the World of 1st Studio and Masha & Veronika Babko The 1st Studio, also known as First Studio, appears to be a production company or a creative team that produces adult content. Within this context, Masha and Veronika Babko are two individuals who have gained attention for their work. Who are Masha and Veronika Babko? Masha and Veronika Babko are twins who have collaborated on various projects, including adult content creation. They seem to have built a significant following and have been featured in several productions. Understanding the "Siberian Mouse" Moniker The term "Siberian Mouse" might be related to the twins' origin or a creative persona they've adopted. Siberia is a region in Russia known for its vast landscapes and harsh climate. The "mouse" part could be a playful reference or a character they've developed. What is "Hard 40"? The term "Hard 40" might refer to a specific type of content, a challenge, or a milestone. Without more context, it's difficult to provide a precise explanation. However, I can suggest that "Hard 40" could be related to a:
Content rating : In some adult content communities, "hard" refers to more explicit or intense material. The number "40" might indicate a specific level of intensity or a rating system. Challenge or achievement : "Hard 40" could represent a challenge or a milestone achieved by Masha and Veronika Babko, such as completing a difficult project or reaching a certain number of followers.
Updates and Latest Developments As my knowledge cutoff is March 2023, I might not have the most recent information on Masha, Veronika Babko, 1st Studio, or the "Hard 40" topic. I recommend checking the latest updates from reliable sources or the official platforms where Masha and Veronika Babko share their work. Conclusion
To provide a helpful response, I'll need to make some general assumptions about what kind of content you're looking to generate. If you're looking for a description, summary, or perhaps a script for a video/animation update (denoted by "40 upd"), here are a few ideas: For a General Audience:
Introduction to Siberian Mouse Masha and Veronika Babko:
"Welcome to the enchanting world of Siberian Mouse, where Masha and her friend Veronika Babko take you on adventures that are both entertaining and educational. In their latest update, number 40, get ready for new escapades that promise to delight both children and adults alike."
What's New in Update 40:
"In this special 40th update, Masha and Veronika Babko have prepared something extraordinary. From exploring the vast Siberian landscapes to engaging in fun and interactive games, each moment is packed with excitement. Learn more about their journey and the lessons they share along the way."
For Fans of the Series:
Deep Dive into Update 40:
"The anticipation is over! Update 40 of Siberian Mouse is here, and it's bigger and better. Masha, along with Veronika Babko, dives into new challenges and adventures that test their courage, wit, and friendship. Don't miss out on the thrilling moments captured in this latest episode."

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. |
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
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.
This software act as the floppy server with the USB HxC Floppy Emulator.
This program also allows you to convert floppy file images for the SD Card based HxC Floppy Emulator.
Supports many input floppy image file formats: List of the supported floppy image formats.
Notes:
- Supported operating systems :
-> Windows 2000 / XP / Vista / Seven / 10.
-> Mac OS X.
-> Linux.
- The USB HxC Floppy Emulator support is based on the FTDI D2XX Direct Drivers.
