Technical Specifications
Although the BASIC Stamp has the form of a DIP chip, it is in fact a small Printed Circuit Board that contains the essential elements of a microprocessor system:
- A Microcontroller containing the CPU, a built in ROM containing the BASIC interpreter, and various peripherals
- Memory (an i²C EEPROM)
- A clock, usually in the form of a ceramic resonator
- A power supply
- External input and output
The end result is that a hobbyist can connect a 9 V battery to a BASIC Stamp and have a complete system. A connection to a personal computer allows the programmer to download software to the BASIC Stamp, which is stored in the onboard non-volatile memory device: it remains programmed until it is erased or reprogrammed, even when the power is removed.

Famous quotes containing the word technical:
“The axioms of physics translate the laws of ethics. Thus, “the whole is greater than its part;” “reaction is equal to action;” “the smallest weight may be made to lift the greatest, the difference of weight being compensated by time;” and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.”
—Ralph Waldo Emerson (1803–1882)
