Yes
Novell Dedicated Servers used the 186

Just an aside - are you sure there was an 80186? I thought the '286 was the direct successor to the 8086/8088 processors (which were essentially the same, just commercially distinct). The "Mark 1" aspect was just implied by specifying the "Mark 2" aspect of the 80286.

At some point Intel developed/exposed a RISC instruction set, I thought it was the 486 The family goes (from memory)
8080 8085 8088 (IBM PC) 8086 80186 80286 (IBM AT) 80386 (Compaq) 80486 Pentium
As for a 'RISC' core, all CISC processors have a RISC core (microcoded or hardwired) In my definition a RISC processor executes instructions in 1 cycle, and as such I think you'll find the majority of the pentium instruction set RISC, though it has a CISC family lineage

Thanks Neven, but I think you'll find that the 486 was CISC as were Pentiums, starting with the Pentium Pro the Intel went down the CISC interface / RISC core (where complex instructions were broken down into a reduced instruction set making them more easily pipelined) - they obviously could not just go RISC (like the PowerPC) due to the fact that it would make them incompatible with the x86 instruction set.
But it has been a long time since I studied this kind of stuff so I could be wrong (and hopefully forgiven).

My understanding is the the 386 was a CISC the 486 introduced a RISC instruction set, For what it is worth you may consider a CISC instruction as a series of RISC instructions (microcode) in fact this is how they are implemented
