That worked. But for the less technically minded (ie 727 pilots!

Yes, the base computer only had 8K and a good deal of that was used by BASIC. The CompuNav I got has a Tandy branded 8K memory expansion module, but I don't know if those came standard or were an optional extra or perhaps added by the owner at a later date. Think of it a whopping 16K in your pocket!
The nice thing about this era of Casio pocket computers is that they had 10 separate program memories. You could have loaded CompuNav into Program 0, and created your own programs in 1-9. They also have a databank type feature. In school I kept my electronic formulas in the data bank and then loaded them into the 'solver' which would prompt for variables and solve equation. Very handy. ('Solver' is not correct name but as close as I could get from memory.)
