    DAC Attack! for ZuluSCSI Audio

    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.

    DAC Attack! for ZuluSCSI Audio

    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...

    DAC Attack! for ZuluSCSI Audio

    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...

    SCSI Terminators: Determining Passive vs Active

    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!

    SCSI Terminators: Determining Passive vs Active

    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...

    Netatalk 2.2.8 Released

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

    Announcing ZuluSCSI - A file-based SCSI device emulator

    That's perfect, thank you!

    Announcing ZuluSCSI - A file-based SCSI device emulator

    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.

    GreenSCSI

    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...

    68net - a modern SCSI to Ethernet board

    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.

    68net - a modern SCSI to Ethernet board

    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...

    68net - a modern SCSI to Ethernet board

    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...

    Anyone have a Focus EtherLAN SC-T?

    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.

    SCSI to Ethernet Adapter on New Hardware

    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...

    SCSI to Ethernet Adapter on New Hardware

    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...
