ARM HP-12C devkit and cable?

[d b]

With this interest, and all that room in the ARM, I wonder if someone will ever make a combination 15 / 16, with various alpha labels thrown in?

Lets see; AbCcdeFGHhJLnPU and sort of Y are possible and things like B, I & O would be obvious if used to prompt or label output, using ? and =. No way to make that beautiful angle symbol that the 41 makes, but it could abbreviate "AnG"

No T or V though. Gonna be a bunch of sad surveyors out there.
