What is a 6502 assembler?

6502 assembly is a very low-level language that works specifically for the 6502 microprocessor — a very popular processor from the 1970s.

How the 6502 works?

A computer bus has the job of transferring data and signal around the machine. For a 6502, they are three of them: If you want to carry more data than that two separate signals will have to be sent down the bus. This means you can transfer the number 00011000 in one trip, but 00110001 00110101 will take two.

Why is it called 6502?

The four-digit date code indicates it was made in the 45th week (November) of 1985. The MOS Technology 6502 (typically pronounced “sixty-five-oh-two” or “six-five-oh-two”) is an 8-bit microprocessor that was designed by a small team led by Chuck Peddle for MOS Technology.

What do you need to know about Assembly 6502?

Defining data with DB, DW and DS…reading values Lookup tables, jumping to locations in Vector Tables, Self Modifying code – code that rewrites itself! Many useful commands were added to the 6502. Lets learn about the extra commands that were added to the successor to the 65c02 and and 6280

Which is the best BBC BASIC for a 6502?

Probably the most modern BASIC available for the 6502 – though it requires a 65 C 02 – is Acorn’s BBC BASIC IV as released for the BBC Master. It can be ported to other 65C02-based hardware by implementing a few of the MOS API entry points it relies on, and dummying out the rest; several people have done so for home-built SBCs.

What did the 6502 microprocessor do for computers?

Learn how computers work by building and programming a computer with the classic 6502 microprocessor. This was the first truly low-cost microprocessor that started the personal-computing revolution.

What is the Arduino code for the 6502 bus?

Arduino code for inspecting the 6502 bus from the first video: 6502-monitor.ino Python script for generating the ROM image with the LED blink program from the second video: makerom.py Assembly program for blinking LEDs from the third video: blink.s Long and inefficient “hello world” assembly program from the fourth video: hello-world.s
