Product Description
3 ISA Slot Computer for Legacy Hardware
The RamPC 4U Rack Mount 3 ISA Slot Computer is designed for industrial, commercial, and legacy applications that still depend on ISA expansion cards. It provides three ISA slots in a 4U rack mount chassis, allowing existing ISA hardware to remain in service without requiring costly replacement or redesign of specialized equipment.
This system is well suited for legacy control systems, data acquisition equipment, manufacturing applications, laboratory equipment, and other specialized hardware that requires ISA expansion.
Unlike modern computers that have eliminated ISA expansion entirely, this system uses an industrial-class motherboard with native ISA slots and is specifically configured for compatibility with legacy hardware.
Legacy Hardware and Operating System Support
The system can be configured for older operating systems required by many legacy applications and ISA devices. Hardware and operating system options can be selected based on the requirements of your existing ISA cards and software.
Built for Your Application
RamPC Systems builds each computer to order. Processor, memory, storage, operating system, and other configuration options can be selected to meet your application requirements.
If you are replacing an older industrial or business computer, contact us with the specifications of your existing system or ISA hardware and we can help determine the appropriate configuration.
