Nice!
I never had a Radius on my Mac Plus, but when I got a Mac II, I got the Apple Portrait Display. It didn't do rotation, but it was great for coding and word processing. I kind of miss it, even though my modern 32" 4K LCD monitor is arguably better in every way.
Has anyone made a NuBus graphics adapter that can do 4K?
Given that classic MacOS didn't know about high DPI monitors, maybe running at 1080p (2K) would be better anyhow, so same question for that.
