NEC Electronics Inc. is able to accept mask patterns in a variety of formats to facilitate the trahsferral of ROM mask informa- tion. These are intended to suit various customer needs and minimize turnaround time. Always enclose a listing of the code and a complete "ROM Code Submission" form. The following is a list of acceptable media for code transferral.

PROM/EPROM equivalents to ROM devices

Sample ROMs or ROM-based microcomputers

ISIS-II compatible 8" floppy disks

CP/M Digital Research Corp.) compatible 8" single-density floppy disk

Thoroughly tested verification procedures protect against unnecessary delays or costly mistakes. NEC Electronics Inc. will return the ROM code patterns to the customer in the most convenient format. Unprogrammed EPROMs, if sent with the ROM code, can be programmed and returned for verification. Earth satellites and the world-wide GE Mark III timesharing systems provide reliable and instant communication of ROM patterns to the factory.

The following is an example of a ROM code transferral procedure. The |jlPD8048H is used here; however, the process is the same for all other ROM-based products.

1. The customer contacts his local NEC Electronics Inc. Sales Representative, concerning a ROM pattern for the |xPD8048H that he would like to send.

2. Since an EPROM version of that part is available, the |xPD8748 is proposed as a code transferral medium. Alternatively, a |jlPD2716 or a floppy disk may be used.

3. Two programmed |xPD8748s are sent to NEC Electronics Inc., along with a listing and the "ROM Code Submission" form. A floppy disk may also be sent as back-up.

4. NEC Electronics Inc. compares the media provided and enters the code into GE-TSS. The GE-TSS file is accessed at the NEC factory and a copy of the code is returned to NEC Electronics Inc. for verification. One of the |jlPD8748s is erased and reprogrammed with the customer's code as the NEC factory has it. The |xPD8748s, a listing, and a "ROM Code Verification" form are returned to the customer for final verification.

5. Once the customer has notified NEC Electronics Inc. in writing that the code is verified, and has provided both the mask charge payment and a hard-copy purchase order, work begins immediately on production of his fjiPD8048Hs.

Please contact your local Sales Representative for assistance with all ROM-based product orders.
