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 !

refers to a dedicated regional online node operated by Rashtriya e Market Services Private Limited (ReMS) , specifically tailored for automated agricultural marketing and e-mandi operations in Karnataka, India . The "REMSL" prefix represents the corporation, while "54" designates a specific regional market code or regional portal extension. This technology forms the backbone of modern agricultural reforms, allowing farmers to trade commodities, secure permits, and utilize electronic tender systems transparently.
The "4G" designation specifies a four-segment jaw geometry that delivers uniform radial force around the 54 mm diameter fitting, ensuring equal compression of the internal sealing elements without distorting the metal pipe wall. Part 2: Technical Specifications Comparison remsl54

At first glance, REMSL54 appears to be a cryptic code or acronym. Without any context, it's challenging to decipher its significance. However, through extensive research and analysis, we have uncovered several theories that might shed light on the meaning behind REMSL54.
user wants a long article for the keyword "remsl54". This appears to be a specific term, possibly related to a product, software, or component. I need to follow the search plan outlined. I will start with the first round of searches to gather preliminary information. search results for "remsl54" show a mix of unrelated results. The exact phrase search returned no results. Other searches for chemistry, semiconductor, lab, microscope, and review didn't directly reveal a clear definition. The results include terms like "MRPL54", "PSL 54", "LME-54", and "REM 54". It seems "remsl54" might be a misspelling or a very specific term. I need to explore further. I'll open some of the more promising results, such as the ABB documentation, the PSL 54 rifle, and the MRPL54 entry, to gather more context. opened ABB PDF is in Swedish and describes a "REM 54_ Maskinterminal", which is a relay or protection terminal. The PSL 54 is a rifle. The MRPL54 is a mitochondrial ribosomal protein. The search results for "remsl54" are inconclusive. To broaden the search and explore potential typos or related terms, I will search for "remsl 54" and "rem sl54". search for "remsl 54" revealed "Rashtriya E-Market Services Limited (REMSL)" which is an Indian agricultural e-marketplace. This is a strong candidate. There's also a reference to "Remote Selection - (REMSL)" in a Curtiss-Wright manual, and "REMSL" as "REM Sleep Labs". The user's keyword might be a misspelling or a specific code. Considering the ambiguity, I should aim to cover all major possibilities. I'll structure the article to cover REMSL as an agricultural e-marketplace, the REMSL parameter in power wheelchairs, the REMSL science education lab, and the possibility of it being a typo for other terms like MRPL54, PSL-54, or SL54. I'll search for more details on each. search results for "remsl54" are ambiguous. It could be a misspelling of "REMSL 54" which might refer to a specific component or setting. The results show Rashtriya E-Market Services (REMSL), a Remote Selection setting, and a science lab. The user might also be interested in "MRPL54", "PSL-54", or "SL54". I will structure the article to explore these possibilities. I will open the official REMSL website and other relevant pages to gather more detailed information. article will cover the possible meanings of "remsl54". It will explore Rashtriya E-Market Services (REMSL), the REMSL parameter in power wheelchairs, and the Rice Elementary Model Science Lab (REMSL). It will also discuss potential typos leading to other terms like MRPL54, PSL-54, and SL54. The article will be structured with sections for each meaning, explaining the context and usage of each term. Now, I will write the article. keyword "remsl54" leads into a fascinating linguistic and technical puzzle. The exact string "remsl54" as a specific product or model number yields minimal direct matches in the search record, meaning the search parameter itself is likely an artifact—perhaps a typo, a fragmented model number, or a concatenation of multiple terms. However, "remsl54" can be logically broken down into two parts: "REMSL" and "54."
(e.g., Is this for a Nursing, Engineering, or Business course?) What is the specific prompt? (What question are you trying to answer?) What is the required length? (e.g., 500 words, 5 pages, or a 10-page thesis?) Are there specific sources? (Do you have data or articles you need to include?) Once you share those details, I can build the outline write specific sections like the introduction and conclusion for you!

As the internet continues to evolve, it's possible that REMSL54 will remain a lasting mystery or eventually reveal its secrets. The term may become a cultural reference point, symbolizing the intrigue and curiosity that drives online discourse. Alternatively, REMSL54 might fade into obscurity, only to be remembered as a fascinating footnote in the annals of internet history.

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.

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.
