Are you really certain of this date?
It could be a patent date I am sure the 286 was not available until 85/86
Nearly all had the 8086 which was apparently 2 x 8080(?) back to back
There was a 186 that was a bit of a flop but it could access 1 Mb and more
RAM. This was grabbed by Research Machines and then they conned the GLC to
put them into all London Schools because they looked like real computers.
