Greetings
Boeing is known for having two colored cockpits, Brown (757, 767,777,747) and grey(737) so you will have a brown box (HWL FMS) or a grey box (Smiths) So I dont think that Collins would have any FMS on Brown cockpits, having said that, I dont think either that we can create circles ( a part from hold entering 0 for the leg lenght) since circle (radius to fix leg type) were not in the ARINC 424 -7 protocol which is the protocol used in the old box.
