A rare glimpse into the hardships of terminal emulation development. Here is my office... erhm... living room. The first thing you may notice is that I have a real VT220 to compare against. To the right of the terminal is a Raspberry Pi 4 running the VT100 simulator.
I previously mentioned PDP-10 and ITS. On the far right is an emulator for the Knight TV, a very early bitmap display system attached to the MIT AI lab PDP-10 running ITS.
Not pictured: Datapoint 3300 emulator displaying Guy Steele's CROCK.
