the PROM.
Also confirm that the mask option ROM code data are stored in addresses 7FF0H through 7FF2H.
To develop the programs for the PD6124A and 6600A, use the PD6124 because the PD6124A and
6600A are not available as the target devices for assembly and emulation.
The upper limit of ROM addresses is different in the PD6124A/6600A and PD6124. Make sure that
the program does not exceed 512 steps by checking the end address of the assembly listing after
assembling the program.
The mask option of the PD6124A/6600A is the same as that of the PD6124.
When using "UPDPROM" select "27256" for PROM TYPE.
