I have an atari Falcon basic 4mb model with a HD. I would like to upgrade the ram and I can see internally that this is on some kind of daughter card but has what appears to be a simm / Dimm ? single chip which maybe can be upgraded ? also is there anyway I can increase the resolution that I can work with on my Falcon ? I have a VGA monitor that works with it but its limited to the 640 screen. Finally anywhere where I can purchase upgrades such as the ct60 from ?
