It is easily understood that you assume your custom ISA Slot-compatible devices are ready to kick the bucket. Its true PCI and PCIe have all but taken over the consumer and industrial markets and developers offer less native ISA support, but I can tell you that it’s not over yet! The big hardware companies have been actively pushing the ISA bus out for over a decade in favor of new technology but they aren’t offering to support your legacy ISA cards.
Luckily there are plenty of skilled vendors who recognize your needs. https://trailer-track.com/ A specialized provider of Industrial Rackmount Computers can easily configure a brand new system featuring the latest motherboard or passive backplane technologies with several ISA slots for your device cards. You can dust off that old system in the corner and replace it with a super fast Intel® Core(TM) 2 Duo or Intel® Core(TM) 2 Quad system without losing your ISA support.
There’s plenty of incentive to keep those ISA cards running. It’s possible the manufacturer doesn’t support it anymore or might not even be around, so goodbye upgrade and tech support. Maybe you want to save lucky neko on the R&D time and money it’ll take to redevelop your software, drivers & devices.
