Specific questions.
I believe you need to download the current ROM, modify a few bytes to correct the 16C emulation, and then resend the updated ROM back to the calculator.

Is there a sheet documenting these items?

Have the pre-orders been sent out?

Could you take the downloaded ROM and update a recent 12C to 15C software? (Curious question)

Greatly appreciate the home-grown efforts also.

Answering your questions:

• The cable does not come with instructions - these will be put in http://www.thecalculatorstore.com website, although there are already quite good instructions in HPmuseum.org. I'll try to avoid plagiarism !
• Preorders are being sent out - hopefully all sent by Monday
• Yes, you can take the downloaded ROM and put in a latest generation HP12c. In fact the firmware was originally tested on a HP12c. We have also created HP15c overlays - but not enought to put for sale
  

These calculators are far more robust than the LE - I have probably upgraded firmware on 150 units and none is bricked. I could not say that of the HP30b or the HP15c LE !!
