The 486 SLC2/66 chip is manufactured by IBM, as is the Alaris motherboard.
It is NOT the Cyrix CPU.  The floating point FPU is external, and
the onboard cache is 16K compared to the Intel 8K.

Mine has worked perfectly for at least six months now, with all
applications.
It is not as fast as a 486/DX2, but it is faster than my other 386/33 (Intel).
I am quite happy with it.
