By the way. Actually, two important reasons why I didn't continue on that repurposing project is that: the rev 2 I have at hand seems to be quite rare compared to rev 1. Worse still, both models are notorious for a number of QC issues: Bad LCD flex contact, bad keyboard contact, keys stucking, and more.
Those problems can be fixed by reheating, alcohol washing, etc. But it makes repurposing very difficult for an average user compared to that on the HP20b.
As of today, the easiest way to obtain a rev1 12C+ is to search for "HP 12C for parts" on eBay. Most of those units you see with missing LCD segments are 12C+.
