Sitenotice: 11/29/2018: The wiki is back. It turns out, some anti-virus product on my web server had an issue with the latest version of PHP. My server techs have resolved this issue, and things should be working again. During the investigation, I did restore to a backup from September. There is a chance that any changes done since then were lost, but I do not recall any edits. --OS-9 Al

8/30/2016: Massive re-work is being done on the InfoBox Templates. Read that page to keep up with the plan for that, and adding better keyword tags (categories) to all the pages. --OS-9 Al (talk) 15:28, 31 August 2016 (CDT)

About the Hardware Info Box

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.

Older information:

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 set out to alleviate the problem by designing a Color Computer Floppy Disk Emulator, 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.

Darren has a blog where some basic info is currently stored. A real user manual is available here.

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. Check here for a review the review.
