Pentium III 450 Katmai
Got one of these. It is an SL37C. Worked perfectly. It should be sold and replaced soon.
This was in my first pc, still have it
The first pc i got had this cpu in it, mainly used it to browse the web (on dial up) and to play some games like CS. One thing i remmber about this cpu, or at least mine anyway, was that it would heat up alot even when idleing, had to bolt a 80mm fan to the HS.
