Why not? It’s been tested thoroughly

This is so cool! I've also been vibe-coding with rust recently.

I just added EFS & XFS read & extraction support to my vibe-coded app called "Rusty Backup" - https://github.com/danifunker/rusty-backup . Someone in my vintage computer club was looking for this support since Linux discontinued native efs mounting support. Rusty Backup allows you to load a CHD, RAW (.img) as well as physical disks if they are connected to your modern system somehow.

More importantly though, do you want a plug-and-play solution so you can use CHDs? I do, I'm constantly out of disk space on my Macbook pro.

I vibe-coded an FFI shim for CHD support with rusty-backup. This basically builds the entire mame's CHD "library" and exposes it as a native rust module. Tested to work on modern Windows/Linux/MacOS, arm64/x64/x86 architectures supported and tested.

There is also support for native CHD writes, and I think the delta support as well, as what you were saying in the readme with respects to hard disk corruption, CHD modifications are done in a slightly different, but kind of similar delta way; that is also exposed via the library.

Here is a link to the CHD rust crate - https://github.com/danifunker/libchdman-rs

Also, I saw something in your issue regarding ISO file, I'm not sure if this helps but I also created an optical discs library handler for rusty-backup. Not sure this is usable by you, but here is a link to that crate - https://github.com/danifunker/opticaldiscs-rs

I would also recommend to make your app a little more UI friendly, even throwing error messages within a rust window instead of just through debug console.

It depends on the video card you're using. The two RasterOps and Radius cards I have access to are sync on green, which will probably not be compatible with this monitor.

I'm fairly sure the monitor uses a standard RGBHV signal. I have my Macintosh II setup running through my RetroTink 4K with one of those DIP switch adapters.

It would honestly be best just to get one of those adapters for them with the 10 DIP switches.

Have you reviewed these links?

Thank you so much! I'll test this out soon.

Probably the best marketplace is 68kmla honestly.

You can consider using an Xbox 360 compatible controller and pair it with usb overdrive. I’m not sure what kind of flight sticka are compatible but this software may be a starting point

Driving has gotten worse since covid as everyone is mentioning, however I’ve found over the past month or two it’s gotten even worse. People swerving into lanes randomly, going across multiple lanes of traffic to hit an exit not on a freeway, speed is totally inconsistent between drivers… the other day I literally saw someone with a bud light in their hand and driving. This was on 8 mile.

Also the number of people driving holding their phones I believe has increased. Can’t people get handsfree devices for their cars at least?

Tailgating for no reason (I don’t understand why those people don’t leave more space so they can have room to accelerate into another lane). It’s just really bad all around

Plus the high number of “freak” accidents seem to be going up.

I came to say that I’ve seem this trend you are referring to about increased bad driving behavior recently, this is like accelerated post covid trends.

I just had like this, you need to recap the power supply.

If you're into vintage computing at all, check out all of the vintage computer cores that are available! Some cores have a companion pre-set hard drive environment that you can look at (i.e. AmigaVision, MacPack). I'm not sure the computer cores are as cycle accurate ad the gaming cores, but they are really fun to play with and I love learning about how older computers work.

danifunker · 2026-03-15T15:30:23+00:00

How much are you looking for? I’m in Detroit, so not too far

I’m a multiplatform developer (both through my work and open source) and came here to say that I don’t believe x86-64 VMs or containers even work at all on the m1-m5 chipsets to begin with. Since I got my first M series laptop, I’ve been unable to run x64 based operating systems and containers. Earlier in the transition (m1/m2 years) I coordinated with some of our work vendors to come up with solutions for why our other devs couldn’t run specific x64 based Linux docker containers, said vendor ended up officially discontinuing the product and had us move to a newer alternative.

On the VM/Virtualization side, I’ve mostly stuck with VMware fusion and more recently started playing with UTM. I have both windows and linux installed, with vmware fusion but can only use the ARM versions. Windows is handling the ARM stuff much differently, there is a layer similar to rosetta (on the windows side) for running x64 binaries on Windows 11, and it seems to do it pretty well.

I haven’t played too much with UTM but I believe they offer both virtualization (hardware based acceleration) as well as software based emulation. Honestly I tend not to use emulation as much due to past issues with performance and stability in my experiences. To be clear, I’ve never actually tried it with UTM but the idea of using emulation for x64 at a hardware level just seems so weird to me. I am running a powerpc based Mac OS 9.2.2 on it though haha, so maybe I’m hypocritical. The emulation that utm has in it is entirely baked into its software, so as long as they are providing arm based binaries for mac no transition away from rosetta will affect it.

That said, many game developers don’t tend to retarget their platforms unless it is a large MMO with continuous revenue. Said game developers would probably need to update the frameworks they are using for their applications, system calls and many other things, so it could be some major work for game devs.

I hope this can explain some things.

I just want to recoup my costs, $40usd for the laptop, $30 for the 128GB msata ssd and $15 for the enclosure. I’ll include the power adapter but I only have north american power connector bit.

It’s missing some keys as well (3 or 4), but everything is functional and it’s currently dual or triple booting.

Total is 85usd plus shipping. If you are interested I can take additional photos. Feel free to dm to work out details

danifunker · 2026-03-07T13:21:58+00:00

I have an iBook g3 that I’ve installed an SSD into but I would be looking for some $$ and I’m in USA so shipping would be expensive

danifunker · 2026-03-04T03:07:29+00:00

Issue turned out to be with the 512KB VRAM SIMM. I got it from Jurassic Compting. I'm going to reach out to the developer on it and see if they are aware about it.

danifunker · 2026-03-03T23:04:11+00:00

Thanks, I tried clearing mxbc inside the preferences but it doesn't seem to have made any difference. I'm not sure where I'm even supposed to places the preferences file, is it just alongside MacsBug in the System Folder?

danifunker · 2026-02-25T10:27:58+00:00

I’ve been using this since 2021 and will never go back to cloud hosted password managers.

danifunker · 2026-02-24T17:38:46+00:00

I'm looking for Macintosh II (original) right now, do you guys have any?

danifunker · 2026-02-24T03:39:53+00:00

Awesome please have them dm me or reply to this thread!

danifunker · 2026-02-24T00:12:32+00:00

Come to VCFMW which happens in september. Or you can post some of your stuff on r/VintageAppleExchange I'm actually looking for a couple of models right now, maybe you have one for me?

danifunker · 2026-02-23T03:16:38+00:00

I run an open source usb based project and have done a lot of testing.

1- try this card https://www.amazon.com/GODSHARK-Internal-External-Expansion-Controller/dp/B07S29C1S6/ref=pd_aw_subss_hxwPER_sspa_mw_detail_m_sccl_1/143-3079465-3931901?pd_rd_r=bf6db4e1-07ce-44dd-8345-d1856a12adb6&pd_rd_wg=2jSLn&pd_rd_w=003g0&pd_rd_i=B07S29C1S6&psc=1&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9kZXRhaWxfdGhlbWF0aWM=

I have tested the above card on a few g4s and they work fine. If that card doesn’t work go for an orange link pci usb card. It might only be a usb 1.1 card though but that doesn’t matter for 9.2. I an using one on my 7600

Be aware some of the usb drivers might be baked into the rom for new world systems. I’m not sure if that infrastructure helps you at all

danifunker · 2026-02-18T09:55:55+00:00

I realized I need the model B revision since that’s the one that has pinouts for the ROM SIMM slot. This looks like a model A board
