As Anni Domini pass, I have chosen to relocate my navigation related programs that have been mentioned on NavList in the past.
Astron, my general utility for sextant users, is now here.
My Traditional Bygrave Slide Rule emulator is now here.
My emulation of Gary LaPook's "Modern Bygrave Slide Rule" is now here.
My configurable emulation of dedicated linear slide rules for sight reduction, as discussed some time ago by Bob Goethe and Sean Johnston, is now here.
Apologies to anyone who has tried to access any of these during relocation over the last two days. I have only received one brickbat!
Bill
