@aplmak SCSI tape drives are not supported in initiator mode at this time. While there's certainly no purely-technical reason why you couldn't implement this in the firmware, it's just not as easy as it may appear on the surface, since the SCSI command set for tape/streaming devices is an...

It's now been a couple of weeks since we launched ZuluSCSI Wide, our latest and highest-performance ZuluSCSI model to date, and I'm excited to share what we've been working on for the last several months. ZuluSCSI Wide, our first 16-bit Ultra Wide SCSI emulator, enables read speeds of up to 33...

For anyone who comes across this thread in the future, this ended up being an assembly issue, which was fixed by sending a replacement RM2 module to @KI5NYZ

@KI5NYZ are you able to fully boot without the RM2 module installed? You say "System 7.5.3 boots but locks up while populating the desktop with icons" but are you able to fully boot when the RM2 module is not physically present? Which model of machine are you booting when it doesn't work? Is it...

Support for 16-bit CD audio emulation, for starters. The current optional DAC boards sell for $5 But as @finkmac also points out, it blasts the bits :)

Given the host/controller-side speed/throughput limitations, It may or may not, but it may be interesting to see the https://github.com/ZuluSCSI/ZuluSCSI-firmware/releases/tag/v2025.04.10 numbers and see how they contrast with the previous batch, using the same SD card. FWIW, another ZuluSCSI...

Since there's never been an Atmel-based ZuluSCSI, can you clarify which model you're specifically referring to? I presume you have a ZuluSCSI V1.1, which used the Gigadevice GD32F205, an improved STM32F205 clone. It's printed on the board. Also, which firmware version was on the ZuluSCSI...

Our EU reseller has ZuluSCSI Blasters in stock now.

Thanks! We're working on it.

Nope, it will fail, as it should :) Whether the OS handles that properly or not is up the OS.

@David Cook We just fixed a long-standing bug in the ZuluSCSI code base related to this, and I've cut a development preview release. Now, if you set the read-only permission flag on an image, it is properly exposed as read-only when the MODE SENSE command is issued by a host machine. This will...

Nope, it absolutely does not mean that. The operating system on the computer still has to be able to understand the filesystem to be able to read/write to it. It isn't magic. That said, with a utility such as HFSExplorer or FuseHFS, you can use the two in tandem to achieve this sort of goal.

Just over two and a half years ago, Rabbit Hole Computing developed and brought to market the first RP2040-based SCSI emulator, which represented our second-generation ZuluSCSI. Since then, we've been hard at work, implementing support for the new Raspberry Pi Pico 2 and Pico 2 Wireless, which...

I'm pleased to report that in the days since this initial announcement, this new functionality has been improved upon significantly, and has now been incorporated into the v2025.01.09 firmware release, the first ZuluSCSI firmware release of 2025. This release supersedes the previous preview release.

There's also an operational USB serial console that logs some basic information about what is going on, which you can connect to using any terminal emulation app. The output will show you the device it detects, as well as quasi-real-time calculated transfer/throughput rates, and any errors it...
