Quick Post: The TI-31 Solar
The TI-31 Solar has the exact same function set as the TI-30 SLR+. The TI-31 Solar predates the TI-30 SLR+ by three years.
I found this TI-31 Solar at a thrift shop in Glendora, California. The price sticker was over the display, so it took several wipes to clean the calculator and get rid of the sticker. Other than that, the calculator works just fine.
Check out my blog about the TI-30 SLR+ from 2014:

Have a great day,
