Writing in assembly for the ISB 8080 involved understanding its registers (like the accumulator 'A', BC, DE, HL pairs, and the stack pointer 'SP'), its instruction set, and memory addressing modes. Programmers had to meticulously manage memory, optimize code for speed and size, and handle I/O operations directly. For example, to add two numbers, you might load one number into the accumulator, load the second number into another register, and then use the ADD instruction. The result would then be in the accumulator. If you needed to perform more complex operations, like multiplication or division, these would often have to be programmed as subroutines using multiple basic instructions. The ISB 8080's instruction set included opcodes for arithmetic operations (add, subtract, increment, decrement), logical operations (AND, OR, XOR, NOT), data transfer (move data between registers, memory, and I/O ports), and control flow (jumps, calls, returns). The use of interrupts was also programmed at this level, allowing external events to trigger specific code routines. Debugging assembly code required a deep understanding of the processor's state at any given moment, often aided by hardware debuggers or simulators. For many, the challenge and reward of programming the 8080 lay in coaxing maximum performance out of the limited hardware. This era fostered a generation of highly skilled engineers who could think at the bit and byte level.
