Dear Chang,

Lets go one by one.

First your Frame software and PC-XT. Well if you have a kid-friend ( I dont know if you have a kid - thats why ) give the hard disk to him. When I did this to my son when he was a kid, you should have seen the smile on his face - he was thrilled.

Next you want to enter the linearization data for all kinds of temperature sensors and make a super-duper MCU temperature controller or something like it. OK lets go one step at a time - just specify one type - and lets see if I can point you to the required data.

( Just for information: Yesterday we bought a Korean ( Autonics make ) temperature controller - it had provision for accepting some 18 different sensors and the control was a full PID implementation and completely programmable. It also has a Analog out ! It was about 90 USD and prices are going down further.)
