I have a customer, a company, they specialized on porting my Sciter on old and exotic platforms to create new modern looking software for them. Win95, old Unixes still getting new soft developed for them.
Another company, behemoth, I would say, with 30000 stuff, using Sciter to make frontend for their old mainframe based system (COBOL I think). Mainframe sends 80x24 terminal screens where the frontend gets fields by x/y coordinates to show it in modern HTML/CSS UI.
You may notice a lot of crazy things in dusty corners of IT.
