Hello everyone! it's my first post here (been lurking here for a while although), My name is Michael and I've bought recently two 600xl. (Owned one 600xl (later an 800xl) as a child). One of them works perfectly, the other one has some keyboard issues... Some keys won't work ( 5,8, T, I, G, K, B, M ,to be precise). According to this thread [http://atariage.com/forums/topic/105170-600800xl-keyboard-variants/] it's the "type 3" keyboard (by AWC, with springs and mechanical switches). I've already detached it from the mainboard and the connector/band seems to be OK. Since it has no mylar I also removed the cap from a "5" key (as an example) to see if the switch works and yes, it does. My question: What to do next?, do you have any ideas? Thanks.
