And where can you program in binary and hexadecimal systems?

Question

Programming

There are different compilers, etc. And where are the programs for binary and hexadecimal systems to program on them? I just don’t understand how they programmed for a calculator in the 50s on these systems (with what help did they write it there?) And how can this be done (write and shove it now? I know there are programmers, but for a computer, let’s write a thread in a binary system or hexadecimal, how to activate it?)

Answer 1

Start with Assembler. You'll understand later :)

Answer 2

code for modern systems is also binary, and can also be written in hexadecimal notation
expand your knowledge in the areas of executable code and compilation

Answer 3

Learn assembler
Learn machine codes
Write a program in assembler
Translate your language into machine code
Write them in hexadecimal number system
Any editor that supports it.
Get a working program.
You can find some emulator of the old device to get a feel for how the veterans wrote the code in 1986

Answer 4

Google hex editors like HIEW
