Specify the name of the product being ordered and the type of EPROMs submitted.
Three EPROMs are required for each pattern.
If at least two of the three sets of EPROMs submitted contain identical data, we will produce masks based on this data. We
shall assume the responsibility for errors only if the mask ROM data on the products we produce differs from this data.
Thus, extreme care must be taken to verify the data in the submitted EPROMs.

Checksum code for entire EPROM (hexadecimal notation)
In the address space of the microcomputer, the internal ROM
area is from address A08016 to FFFD16. The reset vector is
stored in addresses FFFC
16 and FFFD16.
(1) Set the data in the unused area (the shaded area of
the diagram) to “FF
16”.
(2) The ASCII codes of the product name “M38003M6–”
must be entered in addresses 0000
16 to 000816. And
set the data “FF
16” in addresses 000916 to 000F16.
The ASCII codes and addresses are listed to the right
in hexadecimal notation.
