Universal ITX Backplane


Found on tindie, this project seems to be abandoned but files can be found on github. Only populated the correctly placed ISA slot to get a testsystem for single boards. Bug in the transistor placemet, 2 legs need to be swapped. Great use of a NE555 to keep the atx psu running. -5V is generated onboard from -12V. Nice Leds for power. I might try to build a simple ROM based Postcard to fit the internal ISA slots.
