Actually the best alpha numeric calculator available today is the Hp17Bii. However, it is a business calculator w/o trig. The solver would allow you to add your own trig routines, but a memory loss could be fatal as it doesn't have the basic scientific functions built in.
As this is a museum, many of us know better calculators that USED to be available that are now replaced by the super delux graphics now on the market.
The best pocket calculator for a Ti-user to get the features you want are listed below in (MY) order of preference. None are available retail, but would need to be obtained via ebay or a collector.
Hp 27s. It is an unobtrusive, powerful pocket calculator that just might make you give up your graphics. I personally consider it the 2nd best pocket calculator ever made (and I am an RPN user!). It is however, the most costly option.
Casio fx-4000 are all basic scienctifics with built in basic. The 6300 may not be allowed as it has a small graphics screen, although it appears to be a normal calculator. All should be fairly cheap to buy via ebay.
Ti-67. I like this calculator to play with, but limited text abilities, on par with the Hp33s and probably more costly.
An Hp19B would also work well for you, but it might be mistaken for a graphics. It is, but only barely and would normally not be considered a graphics in most comparisions, but that won't help you with a professer who may not let you use it.
There are lots of pocket computers of the 80's, but they would draw more attention than the above calculators and likely get banned also.
The only pocket calculator with the I/O you really want is an Hp41c series (CV really). But you would have to invest in other periphials and equipment and learn RPN as well as work with hard to find and maintain equipment to support comm transfer.
Of the above, you cheapest easiest solution is probably the Casio fx-4000 or 5000 series. If money is not an issue and you want to invest in a real calculational tool, the Hp27s IS THE BEST way to go. I doubt that you would regret it! However, you would regret losing it, should you come to rely on it. It is a difficult (and getting worse) calculator to obtain. That it is much cheaper than many HPs is solely because it IS NOT AN RPN calculator, but uses AOS.
If you are planning to take the EIT in the future, the Hp33s is still probably your best bet as it is the only high end programmable still allowed on this exam.
