[gentoo-user] [OT] ...in search of a program (terminal emulator)

Hi,

I think there is kinda "emulator" or "simulator ...or any other kind
pf xyz-ulator...which simulates the look and feel of old computer
monitors/terminal screens.

But (may be due to lacking language skills) I get too much hits (with
search terms like "analog monitor", "old TV" and such), which have
nothing in common, for which I wanted to search for...or nothing at
all, when I search too specifically...

Who can remember the name of that/these xyz-ulators and can help
me?

Thanks a lot for any help in advance!
Cheers!
