HP-11c vs. HP-34c - differences between them

[Gene]

Started looking at these two (when I stumbled on an 11c picture) because of their similarity. Thought I'd start a list of differences in one place. I'm sure I'll miss some things.

The 11c has these features that the 34c does not:
LCD Display
Unified <- key (clear digits, clear X if not entering digits, delete program step)
Permutations
Combinations
Random number generator
3 more user defined keys (C, D and E)
Hyperbolic trig functions and inverses
Self test includes keyboard test


The 34c has these features that the 11c does not:
LED Display
SOLVE
Integrate
DSP I function
MANT function
CLX key
DEL function
7 more program steps all other being equal (210 vs. 203)
2 more flags (2-3)
2 more subroutine levels (6 total)

Note: this list is updated from subsequent posts below and will be updated as any additional items are pointed out.
