Thanks for these helpful answers Tony!!

My own valuable contribution to the world of calculator electronics is to never again attempt soldering of this nature, so when ready to order I'll send you a machine to have it installed.

The idea of modifying a normal Woodstock power cable to replace the brick with a normal USB A connector is great. Simple, elegant and obvious. Well done Dave Eaton.

Looking forward to this Tony!
