Yes,there was a monitor made for the TT by
atari but its very difficult to find or source.You could try Atari Workshop to if they have one.Failling that an adaptor,they
can be obtained,to convert the the TT's monitor port to PC connection and a VGA
monitor might do the trick.I use this set up on my STE VOLOCE,a highbrid STE which is
a Falcon 030 without the DSP etc!
