ISA Computer Motherboard Specifications

3 ISA Slot Motherboard DetailsRam PC Systems offers thie Industrial class 3 ISA Slot motherboard in either a Mid-Tower chassis or 4U rackmountable chassis. Our customers use these systems with all types of legacy hardware and operating systems. If you have ISA slot devices our systems enable you to get more life from them even after their original PC has failed. While PCI and PCIe have taken over the market and developers offer less native ISA support our systems let you continue using these legacy devices.

Often there’s plenty of reason to keep those ISA cards running. Upgrading to PCI or PCIe is usually costly and often it means changing your software too. In some cases upgrading isn’t even possible because the manufacturer is no longer in business. Our 3 ISA Slot systems provide you with the best of both worlds: a reliable new system fitted with your ISA Slot devices.
