Title: Intel 80186
Post by: TWX on Thu, 12 November 2009, 17:20:58

A friend at work ended up with someone's old component-level kit and among the various ICs in the kit were a bunch of Intel 80186 processors.  He let me snag one.

They essentially didn't use them in PCs.  They contained a bunch of stuff that normally was in the support chipset, so there were some compatibility problems in some areas.  It's in a 68 pin package, and looks like the one on the wikipedia article about them.

AFAIK, they had some backwards compatibility issues with software designed for the 8086. Intel got around this on later chips by basically putting in an 8088 alongside with the main chip.

I seem to remember some Concurrent CP/M machines that were based on that chip. They may not have been backwards compatible in the PC sense, but that wasn't the only market for them back then.

At my school, assembler courses were either taught on 68000 or 8086 and 80186 boards.
