3RIC - 6502 homebrew computer - playtime with Apple II disk emulation
Просмотров 3773 месяца назад
Took a side quest before committing my home brew computer to PCB. I wanted to make sure I could access the Apple II disks. My video consists of me playing games on my homebrew 6502 computer 3RIC. I'm using my new Apple II disk emulation to play games that I couldn't previously play. The disk emulator is running on a Raspberry PI Pico. I had to overclock to 400MHz (crazy), to make it work.

The Apple II was magnificent, the strange dots ment colour, the clicks ment music. You had to have a lot of imagination to play a game, it was just enough what the Apple II showed to give the illusion of a game. For me the Apple II will always be special. Remaking the Apple II could remove the limitations of the system. This is fantastic.

      @@thecodesorcerer Ah yes, the video RAM memory interleaving, effectively reducing the clock speed to 1 MHz. even cycles for executing code, and odd cycles for handling video. Most 6502-based computers have this. Also effectively ruling out any form of overclocking too.

      @thecodesorcerer 3 месяца назад

      CPU gets RAM when clock is high, video when low. It’s VGA instead of composite, so video is 1/16tg the VGA clock. About 1.57MHz. Apple II runs at 1.024MHz. Has caused me so many challenges with Apple II compat. Game controllers, disk, sound all depend on counting cycles.

I believe there were designs based on 6502 with separate video controller and memory etc, but they were extremely expensive and always remained a niche product.

Frame it, put a plexiglass window on it an hang it on the wall.

    A full careful tear down and rebuild sounds valuable but a lot of work, and risky! Could you do the rebuild before the tear down, so that you at least still have the original working one to compare against in case something goes wrong? At the very least, take lots and lots of photos, close ups, different angles, etc - I do that most times that I'm significantly modifying a circuit or decomissioning it, and the photos are so valuable when you later wonder exactly how something was wired up. When you do the rebuild, I wonder whether you can build in automated tests for subsections of the build, maybe driven by a microcontroller at a slow clock speed? It would make it much easier for others following along to check their work, and for you as well, of course, being able to verify each section is working correctly in isolation.

    • @thecodesorcerer
      @thecodesorcerer 8 месяцев назад

      The X16 is far advanced of a typical 8-bit machine. The FPGA based Vera is probably closer to a 16-bit system's capabilities, and really does kinda break the spirit of being an 8-bit retro system. Yes, it's technically 8-bit, but it feels very cheaty in it's implementation, like tacking a 6502 onto a 16 bit board to call it 8-bit... I know that's not an accurate way to put it, but what It really feels like, is the 8-bit guy wanted to make an 8-bit machine, but really didn't wanna let go of the capabilities of a 16-bit machine, and created something that doesn't feel like it commits to either. I still bought one... But now that my money is already spent, I feel like I'd rather have grabbed a Foenix instead.
