A nice compilation of almost 2000 text editors for different hardware including mainframes, 8 bit and video game consoles. Commercial and free ones. Unfortunately some links are old and many screenshots missing.
I’m mainly interested in mainframes.
Not sure if this is very useful, like for someone who just uses emulators like Hercules/TK4- with built in ISPF emulator or even real hardware. Some selected links for PC/Linux/Windows
Also nice CFS and EDT (commercial) for Siemens BS2000, screenshot on page 33
