Kvazar KM1810BM 86
Just like the 8088-clone but in 8086 version. The 8086 CPU's are almost identical except that they work with a 16-bit wide bus instead of 8-bit.
The production date of this chip is interesting. Intel designed the 8086 in 1976 and Kvazar made this CPU sixteen years later! At that time the Pentium was on the design table and both 386 and 486 systems were made for the masses.
