Three EPROMs are required for each pattern if this order is performed by EPROMs.
One floppy disk is required for each pattern if this order is performed by a floppy disk.
Ordering by EPROMs
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.

(1) Set the data in the unused area (the shaded area of
the diagram) to “FF16”.
(2) The ASCII codes of the product name “M37640M8-”
must be entered in addresses 000016 to 000816.
And set the data “FF16” in addresses 000916 to
000F16.
The ASCII codes and addresses are listed to the
right in hexadecimal notation.
