Kvazar is an Ukrainian manufacturer from the USSR-era. They made perfectly matching Intel 8088 and 8086 clones. As seen on the picture they used white packaging with gold-colored pins. I like that color combination!

I've tested this CPU in my ARC 8088 system and it works as a normal 4,77MHz/5MHz 8088 CPU. The only problem I faced is that my 8088 boots up with turbo mode on (=8MHz) which can only be set back to 5MHz a few seconds after booting. This means I have to boot the CPU overclocked (double the clock frequency as normal!) and set it back to 5MHz before it crashes.
