4-banger?

[d b]

A reminder to the would-be repurposers in this thread; the late model 12c has an arm chip and plug so it is theoretically as rewriteable as the 30b. It is missing the (admittedly funkey) second line and huge memory of the 30b but it has a couple more keys and it's pretty too.

The 12c is also not about to be discontinued. There are doubts about the long term availability of the 30b and if it does go away then IMHO, it's a waste of great functionality to turn them into anything less than a WP34s.
