3. RAM: 512 X 8 bits
The built-in 512 X 8-bit SRAM is used for data memory and stack area. The RAM addressing range is from $0080 to $027F.
The contents of RAM are undetermined at power-up and are not affected by system reset. Software programmers can
allocate stack area in the RAM by setting stack pointer register (S). Because the 6502 default stack pointer is $01FF,
programmers must set S register to FFH when starting the program.

4. ROM: 32K X 8
bits
NT68P62 provides 32K ROM space for programming. The ROM space is located from $8000 to $FFFF.
The addresses, from $FFFA to $FFFF, are reserved for the 6502 CPU vectors, thus users must arrange them by
themselves.
