- Open Controller CPU for a compatible 1746 chassis
- Configured with 4 MB DRAM and 10 MB FlashDrive storage
- MS-DOS operating system with no bundled application software in the decoded option string
1747-OCEBCBA brings PC-based execution and SLC 500 control resources together for legacy applications that depend on an MS-DOS system image and local chassis I/O.
Maintenance planning should treat its DRAM, FlashDrive contents, startup files, application software, and serial connections as one coordinated machine-specific package rather than independent items.
Before exchanging the CPU, capture the installed memory options, disk image, chassis fan arrangement, communications, I/O mapping, and verified restoration procedure for the original machine.
Availability, condition, price, and shipping time for 1747-OCEBCBA are confirmed during quotation.
