(Flogging a dead horse here slightly) Just took a look at a previous version of that Intel databook: http://www.bitsavers.org/components/intel/_dataBooks/1991_Intel_Memory_Products.pdf Page 5-56 (Page 325 of the PDF) 27C256 Table 1. Mode Selection Intelligent Identifier - Manufacturer 89H Intelligent Identifier - Device 8DH NOTES: 4. Programming equipment may also refer to this device as the 27C256A. Older devices may have device ID = 8CH So apparently the Device ID change is not specific to the A27C256 "Automotive" rated version, just that in the 1993 version of the databook where I first looked the only EPROMs listed are the "Automotive" ones.
