Since you've taken the time to read this, I'd much appreciate it
that if you do some kind of nifty (or even minimal) modification
to the DR-110, please email me and let me know what you've done,
and if you'd be so kind to provide schemes and/or instructions as
a sort of 'thanks for letting me have the DR-110 schemes Matt'
kind of gesture. Please send em to [email protected] and let me
know if you would mind if I posted them publicly on the same web
site that these schemes are available from. Enjoy, happy modding!
Oh, here's the parts list, painstakingly hand typed by myself.
