In my lab in high school we had original IBM XTs. When we ran "ibasic.com" or "cbasic.com" on them we could then use the command "screen 1" to change to graphics mode. The graphics was CGA but the monitor was monochrome. It was not herculese graphics I don't think. How is this possible? Did IBM sell monochrome monitors that plug into CGA? I never seen such a monitor so I don't know if it exists.
