There isn't one yet. The changes are minimal. The firmware is exactly the same. There are some improvements to the efficiency of the power supply circuitry, but the most noticeable change is that the new ZuluSCSI Blaster Rev2026 board has a laid-down DAC and a footprint for the optional RM2...

As a follow-on to our original ZuluSCSI Wide, which we launched a little over seven months ago, in August of 2025, we're pleased to announce our next Open Source Hardware emulator, ZuluSCSI Ultra Wide OSHW, under the CERN Open Hardware License (Strongly reciprocal variant) v2. The ZuluSCSI...

Have you tried using https://jcs.org/bluescsi/wifi_da-1.4.sit ? It should "just work", but I haven't personally tried it in a while. More details and a screenshot are at https://jcs.org/bluescsi

Performance-wise, there should not be any difference at all. ZuluSCSI Wide OSHW design uses Chinese-brand microSD card sockets and buttons, as well as a different bus transceiver and SCSI termination circuitry.

Approximately six months ago, we introduced ZuluSCSI Wide, our highest-performance 16-bit Ultra Wide SCSI emulator. Today, I'm pleased to announce the release of ZuluSCSI Ultra Wide OSHW, a true 16-bit Ultra Wide SCSI emulator, as a lower-cost alternative to our commercial ZuluSCSI Wide...

Check out our latest USB-C equipped Laptop-sized 2.5" ZuluSCSI Blaster, which is available with and without the add-on RM2 Wi-Fi radio module. DIP switches for initiator mode, SCSI termination, and debug/verbose logging are present. As with all ZuluSCSI products, the debug logging can be...

@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.
