Rochester Electronics (REI) does. They're in the product lifespan extension space and are licensed by the big guys (Intel, AMD, etc) to produce popular products after the OEM has moved on to newer stuff, usually to satisfy contract obligations (e.g. "Must provide 20 years of spare parts", often for military apps). They aren't cheap. Innovasic used to, but I dunno what they're up to since Analog Devices picked them up. Similar biz plan to REI. There's probably an embedded ASIC being sold someplace that incorporates an 8086/8088 somewhere deep down. You probably won't find '8086' mentioned in the datasheet, nor will you likely have heard of the company. These days there are numerous synthesizeable models you can cram into an FPGA. And there's still bins full of NOS chips around.
