I have just completed construction of a 32032 computer. (Details of it are irrelavent). What I would like to know is :- is it normal for the 32201D-8 (TCU) to get uncomfortably hot to touch (Xtal frequecy is 16 MHz)? And if so why is it that the CPU (32032E-10) runs heaps cooler? I don't trust chips that run too hot to touch. The 80186-10 (Intel) scared me quite a bit when I built it into a computer. I could have easily cooked an egg on it. Still can! Thanks for any info you might be willing to give me guys. kevin@latcs1.oz

The 32201 is spec'd at 260 mA, = 1.3 watts, at 10 mhz. It is a nmos type process, so it uses a lot of current. Be aware that most of the power in an IC is used by the drivers, not the internal logic. In particular, clock drivers suck amps. Try a 32C201, if you have access to one. It is cooler. Regards, George Grenley person in charge of stuff National Semiconductor
