The connection between 80C188/80186 and 8087 is possible via a special interface circuit 82188. I've never seen the 82188. I only know him from a small photo. Many years ago I had a message that this chip actually existed, but was only available to military customers. There is an application note (A...

Please note that each component has - schematic symbol - Package symbol The schematic symbol is just a visual image for drawing a schematic. In the schematic symbol, the correct number of connections (pins) is im...
