I was referring the word, 'concept' to that of an 'idea'. Just emulate the idea of a battery backed REU. Meaning that all the VICE developers have to do is to just allow the user to save the contents of the REU for later usage. Just don't bother to actually emulate the battery and whatever circuitry is needed to keep it powered in case the host computer is powered down. Keep it simple here... :) -Todd Elliott ________________________________________________________________ GET INTERNET ACCESS FROM JUNO! Juno offers FREE or PREMIUM Internet access for less!
