Purchase now: Allen Bradley 1747-OCSD10 Solid State Disk
Purchase now: Atlantechdrives provides you the 1747-OCSD10, an extremely rare and highly resilient solid-state memory storage device engineered specifically for the Allen Bradley 1747-OC Open Controller architecture. While 10 Megabytes (10MB) may seem small by modern consumer standards, in the realm of legacy industrial automation, 10MB of pure, uncorrupted, vibration-proof solid-state storage was more than enough to hold a dedicated Real-Time Operating System (RTOS) or a stripped-down MS-DOS environment, alongside crucial C++ execution files and machine control algorithms. The 1747-OCSD10 completely eliminates the mechanical failure points associated with rotating hard disks. By utilizing purely electronic flash memory, it ensures that your critical PC-based automation node survives the harshest manufacturing environments involving severe physical shock, dust, and extreme temperature fluctuations.
Technical Specifications of the 1747-OCSD10
The 1747-OCSD10 mounts securely within the Open Controller ecosystem. It provides immediate, high-speed read access for the CPU, drastically reducing boot times compared to the legacy mechanical drives of its era.

Expert Tips: Operating System Optimization
Working with a 10MB storage limit requires precise software engineering. Expert Tip: The 1747-OCSD10 is designed for ultra-lean, highly optimized control environments. You cannot install standard bloated operating systems on this drive. It is best utilized for embedded MS-DOS 6.22 or highly customized RTOS kernels that require less than 5MB of disk space, leaving the remaining 5MB entirely for your executable control logic (.EXE files) and specific machine recipe data. Ensure that any software running on this drive does not generate continuous, large log files, as the drive will fill up rapidly and cause the Open Controller to halt execution with a «Disk Full» system error.
Installation and Imaging Advice
In the world of legacy industrial PCs, having a backup is your only lifeline. Before installing a new or refurbished 1747-OCSD10 into a production machine, it is highly recommended to create a bit-for-bit raw digital image of the drive using specialized cloning software (like Norton Ghost or modern raw-image tools). Because Open Controller hardware is exceptionally rare, having a raw .img file of your 10MB operating system safely stored on a modern server ensures that if the physical flash memory ever reaches its write-cycle limit, you can instantly clone the OS onto a replacement module without spending weeks trying to rebuild a 1990s DOS environment from scratch.
Frequently Asked Questions (FAQs)
Q: What operating systems fit on a 10MB solid-state disk?
A: This capacity is specifically targeted for MS-DOS, ROM-DOS, or highly stripped-down Real-Time Operating Systems (RTOS) that require minimal overhead to execute dedicated C/C++ control loops.
Q: Is the 1747-OCSD10 hot-swappable?
A: Absolutely not. It acts as the primary hard drive for the Open Controller motherboard. Removing it while the SLC chassis is powered on will instantly crash the operating system and potentially corrupt the file system.
