Subject: [sebhc] H8-4 ATX power conversion (note to self)
To modify the H8-4 for ATX power make sure you strap the 7912 properly. I thought my card was bad but after thoroughly checking my regulator straps I realized I strapped the 7912 incorrectly. The result is not damaging, it basically applies GND to the output chips (instead of -12v) which results in console input working but nothing is output to the console.
