The following operations correspond to the numbers listed in Figure 4:

1. Determine the correspondence between character codes and character patterns.

2. Create a listing indicating the correspondence between EPROM addresses and data.

3. Program the character patterns into an EPROM.

4. Send the EPROM to Hitachi.

5. Computer processing of the EPROM is performed at Hitachi to create a character pattern listing, which

is sent to the user.

6. If there are no problems within the character pattern listing, a trial LSI is created at Hitachi and samples

are sent to the user for evaluation. When it is confirmed by the user that the character patterns are

correctly written, mass production of the LSI will proceed at Hitachi.
