PC Motherboard Diagnostic Card, 4-Digit Card PC Analyzer Computer Diagnostic Motherboard Post Tester for PCI & ISA

Problems...1. ISA voltage and ground lines aren't even tied to the circuit. There is no way this would work.2. No voltage regulator present. If the logic needs 3.3v from ISA then that would be impossible.3. Card is slightly shorter than ISA slots and can plug in off center.4. The included user manual was... not included.5. The PCI part might work but the advertised ISA function does not exist in this device.NOTE: Purchased from Serounder-m, fulfilled by Amazon.
