We have a large number of old AT-MIO-16E3, AT-MIO-64e3; PCI 6023E; PCI 6024E; PCI 6036E boards (probably about 2-5 years old). We want to use these boards in an industrial PCI / ISA housing system; which is supplied with +5; +5sb; +12V, -12V and GND. Is there an obvious way to check if these boards will work in the PCI / ISA housing?. I know you can check the keys on the PXI systems; is there something similar for PCI?
