Where's the old site?
Gone. Things didn't work out with Blitz Studio. I'm not interested in changing the site's domain name, however. It's no longer a website for video games, though Blitz Studio only published one...
What is the site about now?
This is a place for me to host my various programming projects. The current project is 64-DOS, evidently a Disk Operating System for the Commodore 64. Read on to find out more about the project.
What is the current state of development?
I'm almost done writing the terminal program (COMMAND.COM in MS-DOS). In 64-DOS, it's known as DOSTAI (Disk Operating System Terminal And Interpreter). There are a few other components that I need to get started on:
- First-stage boot program (loads the second-stage boot program)
- Second-stage boot program (loads the kernel)
- Kernel (the core of the operating system)
It would take more time than I'm interested in spending to explain why there are two booting stages.
Will it be available for free?
Most likely! I doubt there's a market for this kind of thing, so I'll probably release it free of charge. I might even make it open-source. But that's somewhat less likely. In any case, once it's usable, I'll provide a link for it.
What tools are being used to develop it?
| Text Editor | Notepad++ |
| Programming Language | MOS 6502 Assembly |
| Assembler | DASM |
| Emulator | Versatile Commodore Emulator |
| Diskette Image Editor | DroiD64 |
Additionally, I relied heavily on a lot of reference material...
| Source | What I used it for |
|---|---|
| C64 Standard KERNAL Functions | Identifying which addresses to JSR to in the code |
| C64 Memory Map | Finding specific memory locations in the C64's RAM |
| Inside Commodore DOS | Better understanding the confusing-ass 1541 disk drive |
| C64-Wiki | Getting quick info on anything related to the Commodore 64 |
| 6502 Instruction Set | Getting acquainted with the heart of the C64 |
