	*Most newer ICs use a 'S' designation in the middle of their part number where older ICs used a '-' mark. This is most likely to designate CMOS die fabrication but has yet to be confirmed.		*Most newer ICs use a 'S' designation in the middle of their part number where older ICs used a '-' mark.

	===Note=== Use of "-00", "-DO", etc. suffixes (or no suffix) seems to vary randomly. For instance, an E8 ROM might be numbered 341-0014 or 341-0014-00 and have "E8" stamped elsewhere on the ROM.

	There is some evidence that the prefix "341" vs "342" may denote manufacture or locations, 342 being Singapore. Perhaps it could also denote NMOS vs CMOS die fabrication. Also, 341/342 are always ROMs, and 344 are always custom ASICs.		There is some evidence that the prefix "341" vs "342" may denote manufacture or locations, 342 being Singapore.
