===Notes:===
*Use of "-00", "-DO", etc. suffixes (or lack of suffix) seems to vary randomly and is inconsistent. For instance, an E8 ROM might be numbered 341-0014 or 341-0014-00 and have "E8" stamped elsewhere on the ROM. In most cases, this also seems to apply to "-A", "-B" suffixes (or having no suffix). It has been suspect that "-A", "-B" suffixes could be used to denote IC runs or production batches.
*There is some evidence that the prefix "341" vs "342" may denote manufacture or locations, or first and second source suppliers. Perhaps it could also denote NMOS vs CMOS die fabrication.
*341/342 are always ROMs, and 344 are always custom ASICs. However 343S0061-A is a custom ASIC and does not follow this pattern. So perhaps like with the ROMs, the prefix denotes first and second source suppliers or fabrication process.
*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.

Notes:

  • Use of "-00", "-DO", etc. suffixes (or lack of suffix) seems to vary randomly and is inconsistent. For instance, an E8 ROM might be numbered 341-0014 or 341-0014-00 and have "E8" stamped elsewhere on the ROM. In most cases, this also seems to apply to "-A", "-B" suffixes (or having no suffix). It has been suspect that "-A", "-B" suffixes could be used to denote IC runs or production batches.
  • There is some evidence that the prefix "341" vs "342" may denote manufacture or locations, or first and second source suppliers. Perhaps it could also denote NMOS vs CMOS die fabrication.
  • 341/342 are always ROMs, and 344 are always custom ASICs. However 343S0061-A is a custom ASIC and does not follow this pattern. So perhaps like with the ROMs, the prefix denotes first and second source suppliers or fabrication process.
  • 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.
