Greetings from Friends Cafè. In Monrovia, CA! My favorite place to hang out on Friday nights.
I doubt we see these in office stores anymore: the Texas Instruments BA-20 Profit Manager. I purchased this while visiting the Claremont Colleges Bookstore, after another visit to the Honnold/Mudd Library.
In what otherwise would be a desktop calculator, the BA-20 features Cost-Sell-Margin. To get around the need for a "compute" key that TI's flagship business calculator, BA-II Plus, the BA-20 has three dedicated columns of two keys: two keys for entering known values, the third is calculated for automatically.
Until next time, got to get to eating!
