[Lazarus] Displaying text with colour and insertion point

Does anybody have any suggestions for a component to display status or 
terminal text that will allow limited enhancement (colour, possibly 
underline etc.)?

Over the last few weeks I've been tinkering with an emulator for an 
obsolete mechanical terminal (IBM 2741), including support for the APL 
character set. I started off using a listbox for simple output, noting 
that this didn't have provision for multiple colours or marking the 
insertion point. I moved on to stuffing characters into a memo, this 
allowed me to force a current-position marker but still had no colour.

Looking at the CmdLine component, it appears OK as a command window 
(i.e. accepting keyboard input etc.) but isn't so hot when the principal 
requirement is to display text pushed into the underlying strings 
storage from elsewhere: in particular, there isn't a way to force the 
insertion point marker to the end of what's just been output.

I'm sure I'm not the only person who wants to do this sort of thing: 
does anybody have any recommendations?
