Um... I'm not familiar enough with the USB B_CALLs to say what it is you meant here, but 80ED is a boot B_CALL which displays an error message, clears the RAM and turns the calculator off. Or, if the OS is not marked validated, deletes the OS before turning the calculator off.
And 80ED, like everything else after 80D2, is only available on HW version 2 or later. FloppusMaximus 14:47, 6 November 2006 (PST)
I'm sorry, but I have no idea where I saw this. I've searched high and low for this routine, but I can't find it again. I even checked usb8x to make sure I didn't somehow find my way onto its flash page in Calcsys, but I can't find it. You know more about the real 80ED than I do, so I suppose this should be changed to the real one. Sorry for the confusion. brandonw 16:48, 6 November 2006 (PST)
