[GreenKeys] New Model 15 owner, getting it cleaned up and running!

[Harold Hallikainen]

Welcome to the model 15! I started with that in high school 55 years ago,
and now have a 15 along with 14 typing reperf and TD (Thanks Nick!).

On the 15 "slowing down," how does it sound with no loop current? How does
it do copying its own keyboard?

Good luck!
