Intel Pentium 200
I have two Pentium 200's that are identical except for it's production date. Usually I'll try to avoid getting too much of the same CPU's (i.e. same sSpec or revision) but in this case I found it interesting to have a CPU that is dated week 45 of 1996. The Pentium 200 was released in week 24 of 1996 and was the fastest CPU at the time.
In 1996 the slower Pentium's (75, 100, 120) were still popular as affordable choice. Even 486-class systems were still sold as budget system. It wasn't until 1997 when the Pentium MMX (166, 200MHz) became commonplace.
