ROM number

g 2. Mark specification

Mark specification must be submitted using the correct form for the package being ordered. Fill out the appropriate

80P6N mark specification form and attach it to the writing to PROM confirmation form.

(2/2)

We recommend the use of the following pseudo-command to set the start address of the assembler source program be-

cause ASCII codes of the product name are written to addresses 000016 to 000816 of EPROM.

EPROM type

The pseudo-command

Note : If the name of the product written to the EPROMs does not match the name of the writing to PROM confirmation

form, the ROM will not be processed.

Ordering by floppy disk

We will produce writing to PROM based on the mask files generated by the mask file generating utility. We shall as-

sume the responsibility for errors only if the written PROM data on the products we produce differs from this mask file.

Thus, extreme care must be taken to verify the mask file in the submitted floppy disk.

The submitted floppy disk must be 3.5-inch 2HD type and DOS/V format. And the number of the mask files must be

1 in one floppy disk.

File code

Mask file name

.MSK (equal or less than eight characters)
