The PLATO IV terminals had a 512x512 addressable pixels, local charset memory (Font)
and the ease and power of TUTOR to support them. It still amazes me how much
work and fun we extracted from the limited cpu, memory, storage and communication
bandwidth we had.
Oh and those keyboards. Best damn ones I’ve ever used.
