Still need a display block for it to work. Most old computers used the VGA protocol which allowed each pixel to be addressable in video memory. Wouldn't be too bad to implement since you just need to reserve a memory array to act as a VRAM for each instance of the display block, resized for whatever size monitor you make (preferably 2:1 ratio)

@@elmfer think simpler for a start, a display block that receives a UART signal and is essentially a terminal output. Bonus points for basic VT100 escape character support, but ADM3A would be sufficient enough, would even fit better with the 70s theme as that was the terminal of home users of the time. Then have a serial keyboard and you have your BASIC (heh) 70s home computer setup. For simplicity and QoL reasons have the keyboard check if there is a screen attached to the machine and have it display it as an UI element, much like CC and OC do. Add some sort of storage, could use either magnetic tape or even paper tape to stay with the theme, and you have your retro computing setup done. Could place some premade media in dungeon chests loot tables, like finding a BASIC or a FORTH tape. The Apple 1 wasn't much more by the way. A simple 6502 system, the lower half of the board, connected to a simple terminal controller, the upper half of the board, that could generate a composite signal. It even had just one control character, clear the screen. The boot monitor was a very simple affair that fit into 256 bytes, all it could do was show and manipulate memory and run something in memory. The tape reader module came with its own little ROM. And another thing you could look into, have compatibility with Project Red bundled cables, that way one can have up to 16 IO per side. And think about persistence if you haven't already, what happens when a CPU unloads, do you save its state and reload it on chunk load, what OC does, or do you issue a reset, what CC does. You could also make it load its own chunk, but that comes with its own sack of fleas, especially if the machine is used as a controller for some industrial installation. EDIT: Maybe an option for the future especially for modpacks, being able to disable the editor UI so that one would have to program these the old fashioned way. Write program on ingame development machine, burn to EPROM, add EPROM to MCU version, let it run. If it doesn't work, erase EPROM, fix bug, burn, insert, rinse, repeat. First you have to find a KERNEL EPROM for the computer tough... or toggle in your own boot ROM on a hand EPROMer 😁

The main thing it adds over previous mods is the fact that it's based on a real ISA rather than using a lua interpreter. Otherwise I don't think it can do anything that those couldn't. Also, serious redstoners would _easily_ consider it cheating and would stick with vanilla, or _sometimes_ more limited redstone mods. It's great for learning about the 6502 and assembly though!

Nice Projekt and congratulations that it works so well. I have 2 questions for you: 1. Did you know about the new java ffm/ffi that allows easier access to native functions? If so, why did you decide to use the "old" jni approach? 2. Why did you decide to use imgui instead of a minecraft native gui library?

@elmfer

8 күн бұрын

Thanks! I didn't know about about java's ffm 🤔, and JNI is something I am familiar with for the longest time. And I used ImGui because its design allows me to add UI elements without much effort, so this makes it easier to create intricate IDE for the mod.

My guy using a 6502 as an OR gate, thats absolutely hilarious Incredible work! although i wonder if it would be worth it to port the emulator over to java lol

I'm not sure how you're importing the imgui library exactly, but you should shadow them into a fatjar using a gradle plugin, that way multiple mods can use the same libraries, (mostly) without conflicts, even when using a different version compared to another mod! This works by moving all the library packages to a subpackage of your mod, you'll have seen this behaviour before if you've ever seen multiple instances of a class like "Gson" in the autocomplete list, because multiple libraries depend on it and shadow them separately.

@elmfer

You are right! I did try use the shadow plugin, but the fat jar file it generates uses unobfuscated Minecraft code with it .This is not going to work outside of development environment, so I have to figure out on how to fix that

Interesting, I have long planned to create a Minecraft mod for something similar. However I want to run way more CPUs with high-bandwidth peripherals, and so I want to implement a network protocol to access such an emulator, and just implement a "client mod" for minecraft(-servers). You can distribute screen images etc. via a side-channel(not necessarily via the Minecraft protocol). This also would make it easy to change the emulated CPU architecture, and implement the client mod in a cross-platform way.

Nice work! thats it that i can say.. i'm confused about your things but nice edit and yeah... lol

damn i wanted to do that for a long time but u deserve the win

My hardcore world is on Forge, using Minecraft 1.19.3. It's about 400 days old. And it also has the CC: Tweaked mod installed.

Thanks to the serial communication you can use 4 microcontrollers as three inputs each and use serial communication to talk to a 5th microcontroller. That way you have 12 GPIO instead of 4.

When you used imgui for displaying the colorful texts, what methods did you use to show the styled/colored text in the text editor field? Can't seem to find any way other than implementing that manually or writing JNI code for java to work with a library that does that in C

@elmfer

18 күн бұрын

The code editor can syntax highlight (color text) based on what language is selected, and it uses regex to find keywords and color them. Currently, C++ is selected, but obviously it doesn't work well with Assembly. I do have to create a custom syntax highlighter for it at some point
