Very much like a mechanical typewriter, since that was how
terminals of
that vintage behaved. There's example output at
http://wotho.ethz.ch/APL-1130/2741_APL_Demo.png (it's ETH,
but I don't
think there's a Pascal connection), I've got most of a standalone
terminal emulator that behaves in the same way but haven't got the
colour aspect working due to lack of a suitable component
(and lack os
sufficient skill/experience to write my own).
When you got already that far with Tmemo, try the TRichMemo which is a
TCustomMemo descendant which allows changing font attributes in the text. It
has also a LoadRichText and SaveRichText so that you can save the colored
text to file.
Thanks for that, I'm on it.
