HP-71B Software for navigation

[rprosperi]

Congratulations, both on surviving your initial trip using 'old school' navigation equipment, and also for proven success in re-establishing a working navigation system on your 71B!

Was the final program you used from the Schenk book, from the translated 41 ROM (using the 41 emulator) or some hybrid you created? Hopefully, once enhanced as you suggest above, you'll be willing to post and share your programs - you never know, there could be other brave souls wanting to use pre-GPS navigation too.

Well done Erwin, thanks for sharing your planning and success stories here.
