Please note the following when ordering HD404081, HD40A4081 and HD40C4081 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 2-kwords version (HD404082, HD40A4082, HD40C4082). The program that converts ROM
data to mask drawing data is the same as that used for the 2-kwords version, and therefore the same amount
of data is necessary. This applies both to orders using EPROM and orders using data transmission.
