Please note the following when ordering HD404388, HD40A4388 and HD40C4388 ROM.
When ordering ROM, please fill the "Not used" areas below with all-1 data, to give the same amount of
data as for the 16-kwords version (HD404389, HD40A4389, HD40C4389). The program that converts
ROM data to mask drawing data is the same as that used for the 16-kwords version, and therefore the same
amount of data is necessary. This applies both to orders using EPROM and orders using data transmission.
