So you will need a custom cable or a pin header to card edge adapter to use the Gotek floppy drive with these systems. If you go the custom cable route, I recommend obtaining a Universal Floppy Cable, removing the lone 34-pin connector on one end and crimping a 34-pin IDC female card edge connector on it in the pin connectors place.There are many varieties of these devices and they usually come with a USB port on the front of the unit and a 34-pin header 4-pin power header on the back.While originally intended to replace disk drives in industrial, sewing and musical equipment, they can be used with standard PC floppy controllers.
Floppy Emulator Usb How To Make TheseHowever, as they come they are at best diamonds in the rough, so in this blog entry I will describe how to make these devices more useful for vintage IBM PCs and compatibles.
As they come, these devices only support one kind of floppy disk format. Most support only 1.44MB disks, some only support 720KB disks and I believe one mode does only 1.2MB disks. The device will partition a USB disk into 1000 partitions of the disk size it supports. Then you can copy data onto each partition, insert the USB disk into the Gotek and use the left button and right button to increment the partition by 10 and 1, respectively. The Gotek has special software to format these partitions onto a USB stick and to copy data over to them. As described, the official Gotek firmware has somewhat less than stellar features for vintage PCs. Vintage PCs commonly used seven formats, 160KB, 180KB, 320KB, 360KB, 720KB, 1.2MB and 1.44MB. The floppy disk drive controllers which came with the IBM PC, XT, PCjr. These are the systems where your need to use floppy disks will arguably be at its most frequent. As it comes from the factory, the Gotek is good for little more than using boot disks and installing some programs to DOS. The chip that drives the Gotek is an STM32 ARM Cortex-M with built-in flash memory. This flash memory holds the devices firmware and can be reprogrammed to serve other purposes. There are two third-party firmware projects which can be flashed onto the Gotek to give it more vintage-friendly functionality. Floppy Emulator Usb Free And OpenThe first is FlashFloppy, which is free and open source software. The other is the HxC firmware, but that costs 10 Euro and may not offer a great deal of additional functionality for my intended uses. Both firmwares can also make the Gotek simulate drives intended for non-PC compatible systems. I decided to try out the Flash Floppy firmware. I used this guide to buy a unit which would work with my vintage PCs. Because I was just starting out, I downloaded the stable release version, v2.13. I used the USB-A to USB-A cable method described here to get the Flash Floppy firmware onto my Gotek. You have to give STM Electronics your email for them to send you the download. Floppy Emulator Usb Upgrade Function AndMy Flash Floppy firmware update did not take the first time with the upload function, so I used the upgrade function and that got the Gotek to take the Flash Floppy firmware. The IBM PC Diskette Drive Controller, found in virtually all IBM PCs, XTs and Portables, uses card edge connectors. Almost all 5.25 Double Density drives also use card edge connectors. If you go the custom cable route, I recommend obtaining a Universal Floppy Cable, removing the lone 34-pin connector on one end and crimping a 34-pin IDC female card edge connector on it in the pin connectors place.
