Here is a close up of the etch marking: http://forum.datormuseum.se/data/87681DD5-B816-494C-AA4C-D8DB3FA35406/1913E94E-C1CC-41C3-9F41-D80A1E869950.jpg It says IECU. I wonder if that is some kind of product name? The copyright in the etch is 1984 but the chips are mostly from 1985 or 1986. ----- Check out http://oai.dtic.mil/oai/oai?verb=getRecord&metadataPrefix=html&identifier=ADA152953 which has a lot of clues. Unfortunately Volume II doesn't seem to be online, and would be even more helpful based on its TOC. -----
