older 757/767 - no DSP. Limited eicas system displays off a push button thingy (it's been a while....) giving expanded ENG, STATUS, and that's about it. On the newer ones, with Pegasus FMC's, you can get an expanded Eng display on the FMC CDU by going to MENU-ACMS-DISPLAY-ENG DATA....not well known.
Don't know about the 757-300 or the 767-400.
747-400 is much the same as the 777, without the checklists or the mousepad.
Hope this helps, 'cos it's confused the heck out of me....
