Hi,
1: Will it work with pretty much any CRT or LCD monitor, or are there specific requirements?
It will work with any normal monitor.
Specifically it will work with any monitor that accepts a 31.5 Khz signal.
There are a few weirdo monitors out there that don't accept a 31.5 Khz input. I know because I saw it happen.
Probably any old monitor you have laying around is going to work on it.
The VGA port on all my A3000s has always displayed completely perfect video output all these years. Yay Amber!
