  • math calculations are instant, but menu takes 2 seconds
  • arrow keys not used
  • no constant memory
  • no Mach calculations

Menus

Menus are simple … what you see is what you get. That’s all.

    I was recently given a TechStar by a friend, and it included the manual. I took the opportunity to scan it in, and have the .pdfs freshly posted here: https://haveblue.org/?p=2224
