Type-Speed 89 might be of interest if you do a lot of typing on the calculator and are curious about your typing speed. It's easy to use, allows you to type from your own text files, and shows a lot of statistics. I was surprised to find that my typing speed on the calculator was much faster than I expected. It's worth a couple of tries. I have had it crash a few times, though (mainly around the menu where a text file is selected), so be careful.

There are a few bugs. Certain special characters don't appear possible to type at all (the CHAR menu is inaccessible and some of the normal AMS key combinations for special characters are ignored), which unfairly counts against your accuracy score. Occasionally it didn't stop timing automatically after one minute, and I had to stop it manually. Also, text files with manual line breaks aren't handled correctly—the accuracy score displayed is totally wrong.

The user interface is efficient and easy to use. The menu screen looks cool but makes the text a little difficult to read. The documentation states that the “Options” item isn't implemented yet. Personally, I prefer that features that aren't implemented yet not appear in the menu at all, as it's kind of annoying, clutters up the interface, and can potentially confuse users (although this program does display a message that it's not implemented yet). As this program was last uploaded several years ago, it doesn't look likely that a new version that implements the options will ever be released.

The program size also seems a bit large for what it does. This is partly because the author had not placed the program in PPG format yet, but even then it still seems kind of large.
