Custom Computers for Legacy and Modern Expansion Hardware
Ram PC Systems specializes in new computers built for both legacy and modern expansion hardware. Our systems are available with ISA, PCI and PCIe slots, making them suitable for customers who need to continue using specialized interface cards, industrial control boards, data acquisition hardware, communications cards and other equipment that may not work in a standard modern desktop computer.
Computers for Legacy ISA and PCI Cards
Finding a new PC with an ISA slot or a computer with PCI slots has become increasingly difficult as mainstream computer manufacturers have moved entirely to PCIe. Ram PC Systems offers configurations designed specifically for applications that still depend on ISA and conventional PCI expansion cards.
Depending on the system, configurations are available with multiple ISA, PCI and PCIe slots, including full-height and full-length expansion options. Mid-tower and rackmount systems are available for desktop, laboratory and industrial environments.
Legacy Operating System Support
Some applications require more than the correct expansion slot. They may also depend on older software, drivers or operating systems. Select Ram PC Systems computers can be configured for legacy operating systems such as Windows XP and Windows 7, while other systems support current Windows versions.
Because operating system compatibility depends on the motherboard, chipset, expansion card and available drivers, we can help determine which configuration is appropriate for your hardware and software requirements.
Custom Computers Built Around Your Hardware
If you are replacing an older industrial or specialty computer, the expansion card is often the most important part of the system. We can configure a computer around your existing hardware rather than forcing you to replace equipment that is still performing its job.
Browse our ISA, PCI and PCIe computer configurations above, or contact Ram PC Systems if you need help selecting a system for a specific legacy card or application.
