Dunno how much this'll help, but when I did a poster, I did it using Altsys Virtuoso on my NeXT Cube and set the text using TeXview.app's ``tex eq -> eps'' Service.
And Matej Cepl asked:
Are you using LyX on that computer?
More's the pity, not at this time. I'd dearly love an OpenStep / Yellow Box / Cocoa front-end for LyX though (but the QT version for OS X is way cool / very nice). If I get MkLinux installed on my wife's PowerMac again, I'll use the latter to run LyX, and display / control it from my Cube using Cube-X though.
Interestingly, I first learned of LyX in the comp.sys.next.* groups, a person asking if it could be made to run there...
