monitors for use with old computers.

I'm fairly new to the collecting scene and I'm looking for a monitor I can use with some of my systems. I'm mainly interested in the 8bit home computers, spectrum, c64, atari, dragon, bbc etc I'd like to know if there is a particular type of monitor that can be used on the above machines. I'd like to buy, say one, I can use with all of the above. I know there seems to have been a few different methods used in producing the video signals and, from reading newsgroups, I get the impression that it is sometimes possible to select video outputs/monitor inputs such that, even if the monitor is not directly compatible, a reasonable result can be obtained. Any pointers would be greatly appreciated. -- Pete Robinson pete(a)madhippy.demon.co.uk http://www.madhippy.demon.co.uk - faqs, emulators, links, web utilities.
