Monaco,"Lucida Console",monospace; +--- + +The new [TI-57 Programmable Calculator](/devices/ti57/) emulator, shown below, is the latest addition to the +PCjs Machines collection. + +Even though it's our smallest JavaScript-based emulator to date, it's still packed with goodies: + +- Faithful speed and LED simulation +- Built-in disassembler and "mini-debugger" +- Works on desktop and mobile devices +- Saves and restores state automatically + +Since it saves your calculator's state whenever the web page is closed, and restores that state when the page +is reopened, you shouldn't lose your work. However, just like a real calculator, if you turn it off and on again +(using the **Power** button), then everything will be reset. + +The "mini-debugger" is connected to the Diagnostics window, so you can type commands there as well. +As the "?" command will tell you, available commands include: + + b[c] break on condition c + bl list break conditions + g [addr] run (to addr) + h halt + r[a] dump (all) registers + t [n] step (n instructions) + u [addr] [n] disassemble (at addr) + +Clicking the **Halt** button is equivalent to the "h" command, the **Run** button is equivalent to "g", and the +**Step** button is equivalent to "t". The **Reset** button has no equivalent; it's just a shortcut for cycling the +**Power** button. If you use the "t" command to step through a large number of instructions, the **Step** button +becomes a **Stop** button, allowing you to terminate the step operation. + +In addition to supporting *touch* and *mouse* events, *keyboard* shortcuts are supported, too. The set +of shortcuts is configurable, based on the button *map* passed to the emulator. The default *map* looks like +this: + + "map": [ + ["2nd", "inv", "lnx", "\\b", "clr"], + ["lrn", "xchg", "sq", "sqrt", "rcp"], + ["sst", "sto", "rcl", "sum", "exp"], + ["bst", "ee", "(", ")", "/"], + ["gto", "7", "8", "9", "*"], + ["sbr", "4", "5", "6", "-"], + ["rst", "1", "2", "3", "+"], + ["r/s", "0", ".", "+/-", "=|\\r"] + ] + +Any button that corresponds to a single character can be triggered by typing that character (eg, "+" for the **Add** +button). Escape sequences are allowed, too; for example, `\\b` represents Backspace, which will trigger the **CE** +button. Buttons can have multiple mappings, too; for example, the **Equals** button can be triggered by typing either +"=" *or* the **Enter** key. + +The LED display is configurable as well. The default JSON properties for the LED Device look like this: + + "display": { + "class": "LED", + "type": 3, + "cols": 12, + "rows": 1, + "color": "red", + "bindings": { + "container": "displayTI57" + } + } + +So if you prefer *green* or *blue* digits, change the *color* property. A *backgroundColor* property is supported, +too, but if it's omitted, a transparent background is used. + +Since this emulator is still "hot off the press", don't be surprised if there are still a few lingering +bugs. If you run into any, or you have a browser or device where it doesn't work as expected, +[send me a note](mailto:Jeff@pcjs.org). If your web browser is "old" though, please try a newer browser first. + +*[@jeffpar](http://twitter.com/jeffpar)* +*Nov 10, 2017* + +{% include machine.html id="ti57" config="json" %} + +
