Some of my 11/84 PSUs are not working (working well).
I am trying to find somebody with any skill or knowledge in debugging this hardware - H7202B.
At the very least if somebody could explain to me what signals need to be held low to get the PSU to (try to) start
that would be great.
J5
pin 14 Mod En - leave floating?
pin 17 Ignore
pin 12 hold low - NOT(PWR. REQ.)
pin 11 hold low - NOT(SWTCN)
pin 10 leave floating - NOT(STBY)
I am even less sure about pin 19 - NOT(AIR FLT)
Any clues - of is there a better group for hardware issues?
