ZuluSCSI Pico2 BETA firmware v2024.10.11-pico2-beta

This is a beta "technology preview" of ZuluSCSI firmware running on the RP2350-based Pi Pico2.

SCSI REQ timing has been adjusted for the RP2350's base clock rate of 150MHz. Testing has been extremely limited, but it seems to work reliably now.

Unless you have a ZuluSCSI Pico or Pico Slim with a Pico2 module soldered down, this is of no practical use to you, yet.

Nightly "on-demand" development build

The always-latest development release of ZuluSCSI firmware. These are built on-demand by GitHub CI, and should only be used for testing new features or functionality. Always remember to back up!

ZuluSCSI firmware v2024.08.22

Bug Fixes

• Do not open and write to a log file in raw mode by @morio in #440
• SCSI: fix mac vendor page by @aperezbios in #455, originally implemented downstream by @erichelgeson

Full Changelog: v2024.07.16...v2024.08.22

What Changed in previous v2024.07.16

Bug Fix

• Adjust logic for supported vendor commands by @morio in #434

This allows SCSI toolbox commands to work properly when Apple/Macintosh quirks mode is enabled. Macintosh users can use ScuzEMU to leverage toolbox features, such as the ability to transfer individual files from and to a 'shared' folder.

The ScuzEMU project is fully open source. You can read about it at https://68kmla.org/bb/index.php?threads/introducing-scuzemu-a-scsi-emulator-utility.47750/page-2#post-537509 and download compiled releases for System 6/7+ from https://github.com/saybur/scuzEMU/releases/

What Changed in previous v2024.07.04

ZuluSCSI now emulates 100MB Iomega Zip drives. Image files prefixed with "ZP" will automatically be exposed as Zip drives.

This has been tested on Roland 808 and Macintosh systems.

• ZuluSCSI v1.2-specific: Fix select phase handling for by @morio in #427
• Incorporate Zip drive support from downstream fork in #428 adapted by @morio, and originally implemented by @jokker7718
• Add debug message suppression by SCSI ID in #431, originally implemented by @erichelgeson

Full Changelog: v2024.05.23-hotfix-V1.2...v2024.06.21-BETA

Changes in previous release, v2024.05.17:

• Various Toolbox bugfixes and improvements by @nielsmh in #420, who also took the initiative to author a complimentary utility, escsitoolbox, for 16-bit DOS/Windows 3.x/Win9x which enable direct control of various configuration elements of ZuluSCSI, from within the host OS.

More information, including usage examples, can be found at https://github.com/nielsmh/escsitoolbox/blob/main/README.md.

As of today, here's what the scsitb DOS utility can do:

• Change mounted CD image
• Query for list of available CD images
• List files on shared directory on SD card
• Download files from shared directory on SD card
• Enumerate installed (ZuluSCSI) devices

ZuluSCSI V1.2 hotfix release

This release is exclusively for ZuluSCSI V1.2, to address an issue with the SEL line being detected by the firmware. It resolves a compatibility issue with the MPC60, MPC3000, and quite possibly other sampler devices.

What's Changed

• Fix select phase of ZuluSCSI v1.2 by @morio in #427
