is there a way to do feet and inches addition on ti-85?  i hate adding all of the inches first, divide it by 12, then add all of the feet to get the sum in feet decimal.  there is got to be a way to do it easier on the calculator and get the result in feet and inches.  anyone?   
never, but never question engineer's judgement

buy an hp.  i programmed my own years ago, but there are many online programs for it that have different strengths and weaknesses than mine.  many of our designers have the carpenter's calculators that are specifically made for doing those calcs and i'm faster than them with my program.
the new 50g is quite a capable machine and does accomodate the lower life forms that use algebraic notation...  ;>)

buy an hp?  that is like a totally new breed .  i dont know if i can handle it.

no there isn't.  you can always print yourself off the decimal conversion chart for 1/8" increments.
attached is a listing of a routine i wrote many years ago for the ti-95.  maybe you can transfer it to, (or get some ideas for) the 85.
this calculation is actually very easy to do in your head.  since 1" = .083', then every 1/8" = .01".  it's simple if you memorize the conversion for every integer: 1" = 0.08, 2" = 0.17, 3" = 0.25, etc. for example, 0.26' would be 3 1/8".
oops.  just noticed i said every 1/8" = .01".  i meant of course 1/8" = 0.01 feet.
you guys really need to go metric.
hp 33 (which is approved for the pe exam).
if you hit the "." twice, it will change the number to a fraction.
i switched to rpn about 10 months ago in order to get used to it for the pe exam in april. i will never go back.  
tomfh - if you can make that happen, please do so.  i'd like nothing more than to go to full metric.
tngolfer - rpn is the way to go.  congratulations on the switch.  i managed to get one of our interns to switch and he's happy he did.  he uses a 50g for school, but he says he's getting a 33 for the fe.
