The "generic" standalone UART is the 6402 (different manufacturers put
various prefixes/suffixes on the part). It's available from Jameco
(www.jameco.com) for five bucks apiece. (They also show a part number
TR1863 as equivalent.) It comes in a 40-pin package. It does not have a

can be used for this. I believe Intersil has a 6402 data sheet on their Web
I doubt you'll find this part locally. Nowadays people use
microprocessor-compatible UARTs or microcontrollers with built-in serial
ports. When you finish this project you might want to start to learn
Oh, you'll also need a part to translate the 5-volt signals from the UART to
RS-232 levels -- most likely a MAX232. Someone has probably mentioned this
