8″ floppy drives are the earliest form of floppy drives connected to early minicomputers. By the time of personal computers, 8″ floppy drives had been replaced with 5.25″ floppy drives. But those 5.25″ (and later drives) were still often based on the Shugard interface.
Adrian’s Digital Basement shows how he hooked up an 8″ floppy drive from a TSR-80 Model II to a 386SX computer – and gets it to boot! This is almost certainly something I want to try some day.

It looks like people have been using Raspberry Pi’s to connect and read floppy disks. Below are some of the links. Note that it appears they are only reading data, not writing. See my other posts for both reading and writing to 5.25″ and other floppy drive interfaces.

Have you wanted to read and write data off your old 5.25″ floppy disks with a modern computer? Or how about reading/writing floppies for Apple II, Amiga, ST, or a host of other systems? Or maybe even hooking up a 8″ floppy? It is possible!
There are solutions out there, but they can easily run $100 or more. I, however, picked up the GreaseWeazle and read some of my old 5.25″ disks. Best yet, it only cost $31 Canadian and is one of the more capable solutions. You can supposedly even use your old DOS floppy drive to read/write images for other platforms.
If you’re interested in seeing it at work on some unusual formats, this fellow gives a walkthrough of using Greaseweazle to read 3″ Amstrad disks. Pretty darn cool.
Your floppy drive won’t show up in a command prompt like they did back in the old DOS days or like modern USB plug-in 3.5″ drives. Instead, you have to load and write whole images to the drive in one go. This means you need to work with floppy disk images.
Tech Tangents talks about how preservationists use tools like GreaseWeasle to back up disks.
I learned to program back on an old TRS-80 Model III computer as a kid. Long before Windows and even DOS, most home computers required you type in programs or load them from cassette tapes. If you were really rich, you might afford a floppy drive, but that was an expensive luxury I never had. My next computer was an IBM XT, and it ran the advanced and stalwart DOS 3.30 – which was dramatically better.
Running those old operating systems today requires you either buy one of those old systems and keep it running, or you have to emulate them. You can easily emulate DOS 3.3 and Windows 3.0 and higher on VMWare or Virtualbox, but going earlier than doesn’t seem to be supported anymore.
Enter 86Box – an emulator that lets you emulate REALLY old machines. In fact, I was able to get Dos 3.2 running Windows 1.0.
Here’s what you’ll need:
Floppy disks are a relic of the past these days. You can still see the odd 3.5″ floppy – and there are even still companies making 3.5″ USB drives you can plug into your system today. But 5.25″ floppy drives (360k and 1.2 meg variety) are much more scarce. So scarce, in fact, that you’re likely not to find any outside of an old vintage computer. Most modern PC’s since the Pentium don’t even have connectors, interfaces that support them, and I know of no vendors that make USB 5.25″ drives. Even worse, it appears starting in Windows 10, the floppy drivers were removed from the OS.
So what is one to do if they have old 5.25″ floppies they need to read? Turns out others have had the same problem – so you’re not alone.
Finding cables for your floppy drive can also be a pain. Here are some places you might look, but supplies and suppliers do come and go frequently.
