Intel i486 SX25

This CPU has sSpec number SX411 and is produced in the 51th week of 1991. I have another 486SX25 SX411 that is made in the 16th week of 1994. The 486 architecture was used for quite some time with the oldest systems appearing in 1989. They were very expensive at the time and many people would still buy 8088 or 286 systems. In late 1991 the SX25 was a nice system to have in the average household. However, in 1994 it was already dated.
