## The BACKSPACE key and how to delete typos
The Apple 1 didn't have a typical "backspace" key as we are use to today, due to the way the video display worked it couldn't move the cursor backward to erase characters. So instead it used a "rubout" character, which is the underscore character (__). This character signifies that the input buffer has been moved backwards one character (eg. "PRN__INT" would be received by the Apple 1 as "PRINT").

It takes a little getting used to but you'll soon get the hang of it.
## The Apple 1 only understands UPPERCASE characters
If you're using the PS/2 input you don't need to be worried about this, as we automatically UPPERCASE all typed characters so WozMon can understand what you are typing.
However if you are using the UART and a serial terminal you will need to remember to turn on your CAPSLOCK, otherwise nothing will respond as you might expect.
## Serial Setup
Depending on the baords you can use serial to communicate with the Apple1, some boards require a toggle to be set to select between PS/2 input and UART input. The UART by default will be set to 115200 (8/N/1).
