	~~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.~~		== Description ==

	~~All versions~~ Drivewire ~~and the SuperIDE; CoCoNet and the Micro SD Pak, Bluetooth Pak and RS-232 Pak all suffer from this problem~~.		The CoCo SDC is a Color Computer Floppy Disk Emulator running [[SDC-DOS]] (effectively a floppy drive controller replacement), ready for [[Drivewire]] server communication. It was designed by [[Darren Atkinson]].

	~~[[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, hard to find floppy drives or cassette recorders, it gives direct access to floppy disk, cassette and ROMpak images stored on modern SDHC card storage. This is implemented by SDC-DOS additional commands to mount disk image files on the SD card, program the Flash and execute ROM images contained in the Flash. DriveWire disk support is also included in SDC-DOS.

	[[~~File:cocosdc~~.~~jpg~~]]		Provided your system has a [[Multi-Pak]], you can connect a real floppy interface and the CoCo SDC at the same time, 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]]. It is also useful to backup software loaded from cassettes.

			The CoCo SDC also provides 128K of Flash memory which is divided into 8 banks of 16K 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.

	~~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~~.		Based on an Atmega micro-controller, the CoCo SDC emulates the Western Digital 1774 floppy controller chip and as such is basically 100% compatible with any CoCo software, including copy protected disks. 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. The CoCo SDC aims at aleviating this problem.

	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]].		=== The CoCo SDC case ===

	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.
