<ul>
<ul>
<li>Increase limit of READ/WRITE BUFFER command for improved compatibility on SGI Irix hosts</li>
  <li>Fix firmware version displaying as "0.0" in scsi2sd-util when there is no SD card inserted.</li>
<li>Add new config option to enable blind writes to improve SD card write performance. This was option was previously enabled default but causes problems with some SCSI hosts. This option must be disabled on 68K Macs if there are errors when writing data.</li>
  <li>Reduce some delays for slight performance improvements.</li>
  <li>Use SD High-Speed mode on V6 2021 hardware.</li>

<strong>[22 Apr 2020]</strong>[http://www.codesrc.com/files/scsi2sd-v6/v6.3.1 v6.3.1] New hardware support<br>
<strong>[21 Jan 2022]</strong>[http://www.codesrc.com/files/scsi2sd-v6/v6.4.13 v6.4.13] Bugfix release<br>
<ul>
<ul>
<li>New V6 boards have started to ship which require a different firmware file. These boards are silkscreened with "SCSI2SD V6 / 2020c". These boards MUST use v6.3.1 or newer firmware.</li>
  <li>Fix SCSI writes with sector sizes larger than 512.</li>
<li>Older boards ("Rev F", "Rev C", or "6.02") should use the "revF" v6.3.1 firmware</li>

<ul>
<ul>
<li>Firmware updates on Windows now require the [https://github.com/daynix/UsbDk/releases UsbDk] driver instead of the WinUSB driver. The version of dfu-util that is distributed with scsi2sd-util6 has been modified to work with UsbDk. This should provide a better experience and will resolve issues around driver signing. There is no need to uninstall the previous driver.</li>

SCSI2SD Archived News

Overview

SCSI2SD is an emulator for old SCSI hard drives. It allows replacing one or several old broken SCSI drives with a SD memory card.


Unlicenced Copies

Older versions of the SCSI2SD hardware designs were published under the GPL licence. This permits anyone to build their own board from the original or modified designs, so long as they abide by the licence terms.

  • The source/designs of any modifications must be provided to those you distribute the board to.
  • Clones are based on the obsolete V4 design, lack features, and may not be compatible with all the systems listed on these pages.

Artmix is currently selling unlicensed modified clones ("SD SusanoMonster"), and refuses to comply with the GPL. Please do not purchase this board. If you have already purchased, please request the seller provides you with the modified designs under the GPL licence.

Which version should you buy ?

SCSI2SD V6 This board offers significantly better performance than the V5.x boards by adding support for synchronous SCSI transfers.

Easy access to virtual disk data over USB.

SCSI2SD V5.1/V5.2 This is a newer version of the V5 board, with software-enabled termination, full-size SD card, and floppy-style power connector.

This version provides a faster startup time than V5, which is needed to boot some Amiga and Staubli machines

SCSI2SD V5.5 Plugs directly into an external DB25 connector without a cable. Uses micro SD card.
SCSI2SD V5 This is the older version which uses micro SD cards.
SCSI2SD for Powerbook Designed for Apple Powerbook laptops using 2.5" drives.

Purchase

3rd party accessories

  • Thingiverse Bracket to house both the SCSI2SD card and Gotek Floppy adapter together in one housing by Paul Pritsis.
  • Thingiverse nibblernibbles has created a 3d-printable external enclosure for the SCSI2SD + DB25 adapter. Power can be supplied over USB for hosts which don't supply termination power.
  • SCSI2SD V5 & V6 Bracket by Maya Designs
  • SamplerZone.com External cases for V5.0, V5.1, V5.2, and V6 boards, internal cables for all music samplers, and fully-realized SCSI2SD sampler solutions.

Features

  1. In-built active terminator.
  2. Emulates up to 4 SCSI devices (7 for the V6 version)
  3. Supports sector sizes from 64 bytes to 8192 bytes
  4. Firmware updatable over USB
  5. Highly configurable over USB
    • Selectable SCSI ID
    • Selectable parity support
    • Enable/disable Unit Attention Condition
    • Artificial limits on the SCSI disk size (eg. limit size to 4G to avoid OS bugs)
    • Sector size (can also be set via the SCSI MODE SELECT command, as sent by SCSI format utilities).
  6. External LED connector.
