C64 Assembly - 2024-11-17
Tools, basic knowledge, hello world
Starting on Commodore-64, generally called C64 (MOS 6510 that is a modified version of 6502, will use 65xx here) assembly on Linux. This 8-bit microprocessor is relatively limited and simple, as Z80 microprocessor, and used on several popular platforms, including Commodore PET/VIC20, Apple][, BBC, Oric 1/Atmos/Telestrat, Atari 400/800/5200/XL/Lynx, NES and SNES or PC Engine/TurboGraphix. The power of the most interesing of these computers are in association with their audio, graphics and video co-processors.
This document, is based on the usage of generaly available and FLOSS, xa assembler, xda65 debugger and VICE emulator, on GNU/Linux platforms.
Retrocomputing - 2024-11-12
This picture of "A Mirror of Time" ("Зеркало времени", 1976) animation by Vladimir Tarasov looks a lot like "Q.bert" video game (Warren Davis and Jeff Lee for Atari and Gottlieb, 1982)
This page is about retrocomputing, see also Fantasy Console for virtual neo-retro computers ^^.
Fantasy Consoles - 2024-09-30
Fantasy consoles are 8 or 16 bits like virtual machines, with programming language and that often include tools to add graphics, audio and music. This is a funny world, and a good mean to develop an interactive or multimedia application a quick way. Limited resources, often very simple script language (like Lua as an exemple), allow to quickly prototype things, by only going toward essential things.
