I recently came across a couple of these, but I can't find any info in them. Googling shows me they are an early 80's Microcontroller. But I can't find a data sheet on them for "free" . Using the search bar on the Intel site doesn't even pull up anything.

They are in a 40 Pin DIP package, labeled
Intel (M) (C) 1980

Does anyone know where I can get a datasheet on them or can anyone give me some background on them?
