There is not a TX manual on line that I know of BUT there is a TLb manaul and the only funtional differeances are the TX has a hot shoe and the TLb does not. You can find the TLb manual on Christians Canon FD info site at:
TX's a somewhat rare they weren't sold in Japan basically they are a stripped down FTb with out mirror lock up and the 1/1000th shutter speed.
And yes you want to keep the lens or body cap on to save on the 1.35V mercury battery these use.
