Speed of HP-15C LE - and it's capabilities

[Tugdual]

I completed a version of code for the 34s. I started from scratch so don't even try to compare to the 15C version. I doubt my code is optimal, considering its size and the much higher capabilities of the 34s compared to the 15C. Anyway, here is what it looks like.
I tested it on the 34s emulator and the result is pretty quick. On the real 34s it seems to take much more time; I haven't seen the 1st result after 40mn and I think I'm going to stop to avoid draining the battery.
Edit: took around 1h to find a result.

Usage:
Call A to run.
When it stops you'll read:
FOUND
219,867,435
which means (read right to left) 5/34+7/68+9/12
