... with the GP-1 kit you can connect an ordinary PS-2 keyboard and a common Hitachi-style LCD display to any computer that can use RS232. ... All you supply is an LCD, a keyboard, an optional LCD contrast voltage (depends on your LCD module; often you can simply connect the contrast voltage to ground) and a DC power supply (the GP-1 has an onboard 5V regulator, or you can supply 5V regulated directly to it). Now your Basic Stamp, PIC, or other micro project can have a full text terminal. You can even use the GP-1 to talk to modems (cross cable required) or even a PC.

The Two Line Mini-Terminal is a embedded microcontroller board designed to implement a limited but low cost terminal. The board was designed to be the same size as a 2 line by 40 character LCD such as the OPTREX DMC 40218. With mounting holes in the same pattern as the LCD the controller board can be piggy backed with the display. As an input device the terminal uses standard IBM compatible PC keyboard. In a normal full duplex mode the controller converts the keyboard scan codes to ASCII and transmits them to the RS-232 output. Input from the RS-232 is displayed on the LCD. The software does vertical and horizontal scrolling of the incoming characters.
