Hi,
I saw this post but for some reason thought it was something to do with water temp gauge on your car.
What Cool1 said is the best bet. Check up info on the Dallas 1620 chip. It's a temp detection chip that sends data (9bit) that tells you the temp.
You hook this up to a simple microcontroller, such as the 16F84 or something similar to get the readings from the 1620 chip and to run your LCD display.
Here's a link on how to do something like you want using the Basic STAMP - which is a microcontroller that you can program in BASIC.

Failing that, I'm sure I can come up with some way to get the PET to get the temp and send it to you. 
In any event, check out the Dallas 1620 chip to get some idea of what it is and how to connect it. Also I think Dallas Semiconductor have various applicaiton notes on their site that will provide info on how to use the chip.
Tell Cool1 to move his ass and get his other project out of the way so he can build/program it for you.
SMD is Surface Mounted Device. They're really small and the pins on the chip are very close together. They're designed to sit in the surface of the circuit board, as opposed to the older DIL style where the pins went into holes on the cct board. Unless you have the proper equipment, good eyes, magnifying glasses and a a very steady hand, it's best to keep away from these if possible - especially on the SMD devices which have a lot of pins.
BMS, to me, means Basic Mapping System, which is a method of doing realtime relocation of CICS program maps and code, usually via assembler (for speed and tight code) into virtual storage on IBM Mainframes. I used to write BMS code. I also wrote some of the Box Triffecta code for the NSW TAB. Next time you put your money on a Triffecta you can think of me!
