The Radius and Apple portrait displays (greyscale) were rightly very popular. I still have a Radius greyscale Pivot which is lovely. The only reason that I don't use it is weight -- I don't have room to set up all my Macs so when I pick a monitor, I just grab a lightweight TFT.
As far as using big monitors for programming, you'd be surprised how little benefit you gain. Old IDEs (Integrated Development Environments) for the Mac are very efficient at using desktop space, and I happily learned Think C and Code Warrior C on a compact Mac. Old versions of Real Basic for the Mac are efficient too. By contrast, the latest Windows IDE for Microsoft Visual Studio is just about useable at 1280 x 1024 resolution.
Apple made a monochrome (black/white) composite signal monitor for the IIgs. It was nothing special IMHO and I prefer Zenith green phosphor composite monitors.
