2024-03-02: The wiki ran out of disk space, so things were not working. This has been resolved by adding another 5GB of quota ;-) Thanks to Tim Lindner for reporting the issues. 2020-05-17: If a page gives you an error about some revision not being found, just EDIT the page and the old page should appear in the editor. If it does, just SAVE that and the page should be restored. OS-9 Al (talk) 12:22, 17 May 2020 (CDT)

The CoCoSDC is a floppy drive controller replacement desined by [[Darren Atkinson]]. Instead of hooking up old floppy drives, it uses SD memory cards and disk image files. Since the CoCoSDC emulates the Western Digital 1774 floppy controller chip, it is basically 100% compatible with any CoCo software, including copy protected disks. You can connect a real floppy interface and the CoCoSDC at the same time using a [[Multi-Pak]], then backup physical floppies to disk images on an SD card. Copy protected disks can be backed up using tools like Carl England's [[Defeater]].


Ed "Zippster" Snider is now producing the CoCoSDC interfaces and sells them (as of 12/2014) for $30 as a kit or $40 assembled. They are designed to fit in an FD502 disk drive controller case, but [[Tim Lindner]] has been making plexiglass panels for $10.
CoCo floppy disk replacement devices and software have one major shortcoming – the inability to use software in which the author wrote his or her own floppy disk access routines.

The device gives direct access to floppy disk images stored on and SDHC card, as well as images on a Drivewire server, while allowing use of real floppy hardware - so long as you have an MPI.

CoCo floppy disk replacement devices and software have one major shortcoming – the inability to use software in which the author wrote his or her own floppy disk access routines.

All versions Drivewire and the SuperIDE; CoCoNet and the Micro SD Pak, Bluetooth Pak and RS-232 Pak all suffer from this problem.

Darren Atkinson set out to alleviate the problem by designing a Color Computer Floppy Disk Emulator (effectively a floppy drive controller replacement), based on an Atmega micro-controller. The CoCo SDC also provides 8 banks of flash RAM so users can program their favorite ROM or alternative OS as well. SDC-DOS and DECB reside in banks 0 and 1, respectfully, when shipped. The SDC was designed to fit into a FD-501 or 502 case, as shown below.

Instead of hooking up old floppy drives, it gives direct access to floppy disk images stored on an SDHC card, as well as images on a Drivewire server.

You can also connect a real floppy interface and the CoCoSDC at the same time using a Multi-Pak, then backup physical floppies to disk images on an SD card. Copy protected disks can be backed up using tools like Carl England's Defeater.

Since the CoCoSDC emulates the Western Digital 1774 floppy controller chip, it is basically 100% compatible with any CoCo software, including copy protected disks.

Ed "Zippster" Snider is now producing the CoCoSDC interfaces and sells them (as of 02/2021) for $50 as an assembled PCB or $70 including a 3d-printed case. They are designed to fit in an FD502 disk drive controller case, Tim Lindner also has been making plexiglass panels for $10.

Boysontech also produces the CoCoSDC, see https://boysontech.com/boysontech-a-second-source-for-coco-sdc/.
