Seems like there should be a minimum power requirement that all cpu cards and devices must meet.
okay - so you used the word "devices" which is not part of EOMA68 terminology. sorry i missed this, so didn't understand the question.
*from the perspective of the EOMA68 Cards* the *MAXIMUM* that they are permitted to use is 1.0A @ 5.0v
therefore...
*from the perspective of EOMA68 ***HOUSINGS*** .... * the *MINIMUM* that they must provide is: 1.0A @ 5.0v
above exactly 1.0A @ 5.0v, housings are ***REQUIRED*** to cut power without warning.
This seems like a broken spec to me. Nothing in electronics is exact, so a sane spec should have a reasonable margin between the maximum current a card is allowed to draw and the point at which overcurrent protection is required to kick in.
