The ASIC used in the previous 12C was becoming obsolete, so HP either
had to either re-design from scratch (software wise), or go with
Eric's ROM emulator. They wisely went with the later given that almost
the entire finance industry relies on the 12C, and any numerical bugs
would have unacceptable to say the least.

Yup, if a new 11C or 15C ROM emulated machine comes out, the Ebay
market will drop like a rock.
