Not this guy here. Thanks for the detailed/informative info because it really helps me. When i bought the LC520 when it first came out in Canada i was impressed that so many ( if not all ) the major parts were what i call remove the old and plug in the new without having a PhD and a slew of toools.
Although in the end i have only replaced the battery and RAM. It still works and is used for several PG music programmes that were never ported over to OS 9 let alone OS X and some programmes that require "midi manager" that i can turn on and off with Conflict Catcher and restarts.
