Version 0.2 is now available, featuring: Batch file downloads! You can now select multiple files and fetch them all at once. A progress bar dialog to monitor the transfer, with a Stop button for the impatient. The list of file/image names will now be alphabetized instead of whatever order the...

I appreciate everyone's comments, particularly the kind words about this software being useful. Source is now available on Github at https://github.com/saybur/scuzEMU. Feedback and/or PRs are welcome.

I don't think anyone is claiming a GPL violation. BlueSCSI benefited enormously from upstream GPL contributions. That's absolutely fine, it is part of the reason people license their code under GPL in the first place. However, inserting a vendor specific (and trademark bearing) string into the...

I didn't personally use it, but you may find the command reference at https://github.com/BlueSCSI/BlueSCSI-v2/wiki/Toolbox-Developer-Docs to be helpful as well. One caveat: followed to the letter, that page's advice will vendor lock you to BlueSCSI firmwares only...

Here is the first release of scuzEMU, a SCSI emulator control utility. This System 6+ app can choose mountable removable disk images and download files directly from a compatible SCSI emulator's SD card. I've developed this with a ZuluSCSI running firmware 2024.05.17 (with Toolbox=1 in the INI...

You can tweak the configuration a couple ways, but the "default" way (and what I have been using) is ejecting the disk from within the operating system. That advances to the next disk. There's also new support for an eject button as well using the one leftover pin the audio doesn't occupy.

That's almost identical to what got me going with this project in the first place: I have a small form factor 486 I upgraded to a DX2/66, but it didn't really have room for an optical drive. I figured somebody would have made a Gotek-like device that might work well in its place, and nope...

Over the past few weeks I've been doing some tinkering with ZuluSCSI boards and figured out a way to get a ZuluSCSI RP2040 to output 44.1KHz S/PDIF audio over one of the expansion pins. Combined with some awesome development work from @rabbitholecomputing to add full BIN/CUE support for CD-ROMs...

That's neat, never seen the insides of these before. If note, those look like the same kind of old school tantalums that are all over PC motherboards. If so, hopefully this variety is more robust and less prone to failing short!

Thanks for writing this up, it's quite interesting. I had never considered the constant current draw that passive terminators would have with all those resistors tied to ground. Yet another good reason to avoid them. A pretty common low-dropout linear regulator that looks to have historically...

This is great, it's been awesome seeing new Netatalk 2 releases. Thank you!

That's perfect, thank you!

Is there any documentation about the expansion header available? I was hoping to see what the pinout was and if there were significant differences between the hardware variants.

Another SCSI emulator without bus transceivers, sigh. I get that it makes them cheap and they work well enough without anything else on the bus, but man I wish the people who sold these were more up front about them being totally non-compliant with the spec. If you start attaching real devices...

What I said earlier is wrong: the base Dayna implementation in scuznet came from you, not from me using the Burrows documentation. My apologies, I'm not sure why I thought I had done that. @ronan, if you do want to take a go at this, use that link, it's got great info.

The original Roger Burrows documentation is what I used, which did a good job of covering things. Beyond that, @superjer2000 figured out how to do multiple network packets in a single SCSI transaction, which significantly improves performance - the scuznet thread has talk about that, which I...

Yeah, the Nuvotech driver is kind of a PITA. From the testing I've done, the Nuvo driver offers better performance in some cases, but it's worse than Dayna in others and overall it seems to be pickier about timing on the emulated device. I'd echo @Chopsticks suggestion to ditch Nuvo. I've...

The Nuvolink uses a 12VAC 2A transformer. However, it looks like Focus did some work on the internals and I can't say for sure if the setup is 1:1 on the hardware side. Here's the Nuvolink for reference.

The speeds should be identical in fast/forcefast mode. Under the hood, the firmware is bypassing the FAT filesystem entirely and working with individual blocks within the image to achieve the higher speeds. The danger is that if the image is not contiguous it could start writing random data on...

I've had that happen when the initial bootup scan is not complete by the time the happy Mac shows up. Perhaps look at disabling the contiguous check with mode=forcefast (if that isn't on already and the image is actually contiguous). That might also be a mode option thing - if not specified the...
