</p>
<p>
<strong>[20 May 2015]</strong>[http://imall.iteadstudio.com/scsi2sd.html http://imall.iteadstudio.com] V5.0 boards back in stock!
<ul>
<li>The 3.5" SCSI2SD V5.0 boards are now available for purchase from iteadstudio.com. This arrangement should solve the recent stock availability problems, and provide more flexible shipping options.</li>
</ul>
</p>
<p>
<strong>[4 May 2015]</strong>[http://www.codesrc.com/files/scsi2sd/v4.2.4 v4.2.4] bugfix firmware

</ul>
</p>
<p>
<strong>[26 April 2015]</strong>[http://www.codesrc.com/files/scsi2sd/v4.2.3 v4.2.3] critical bugfix firmware
<ul>
<li>Users who recently received their boards with v4.2.2 firmware must immediately upgrade to v4.2.3, or nothing will work when the default configuration is changed.</li>
</ul>
</p>
<p>
<strong>[20 April 2015]</strong>Sold out, again.<br>
I've partnered with a new manufacturer to build the SCSI2SD in higher volumes, and to sell them direct from China. This will ensure availability and will also improve shipping options.  New boards should be available in a few weeks time.
</p>
<p>
<strong>[31 Mar 2015]</strong>v5.0 boards have arrived!
<ul>
<li>The new v5.0 boards have arrived, and will start shipping from tonight. Pictures coming soon...</li>
</ul>
</p>
<p>
<strong>[23 Feb 2015]</strong>[http://www.codesrc.com/files/scsi2sd/v4.1 v4.1.1] bugfix firmware released.
<ul>
<li>Fix for extremely slow performance in some cases. If the SD card requires 2 attempts at initialisation it would be left running at 400kHz instead of 25MHz.</li>
</ul>
Many users have noticed that I'm currently out-of-stock. I didn't order new boards quick enough to beat the Chinese New Year Holiday rush, and now I need to wait until the PCB manufacturers resume trade. I expect new stock by the end of March.
</p>
<p>Here's a sneak-peak at a new design I've been working on:<br>
http://www.codesrc.com/images/SCSI2SD/scsi2sd-5.0-prototype.jpg <br>
You'll notice this board is half the size, which makes it cheaper to produce in volume.  The power supply has been reworked to be much more efficient, and will allow the new SCSI2SD to run on the terminator power alone. In many cases there will be no need for the power cable. This new version uses the same firmware as the older boards and does not offer any performance advantages. I'm also working on a small 50-pin to DB25 adapter board to replace the current external SCSI2SD.

[[SCSI2SD Archived News]]
<strong>[05 Dec 2014]</strong>
<ul>
<li><strong>Prices back to normal</strong><br>
Prices have returned to normal (with a small adjustment due to AUD currency movement), so please stop sending hate mail.</li>
<li><strong>Bulk order placed</strong><br>
I've outsourced production to a PCB assembly house to satisfy demand. I expect these boards to be ready in early January, but it's possible they'll arrive before Christmas.  In the meantime I'll continue building as many boards as I can and listing these for sale once tested. I'm no longer accepting orders for out-of-stock items, so most people will need to wait for the bulk order in early January.</li>
<li><strong>BETA firmware update available</strong><br>
Testers needed! Available [http://www.codesrc.com/files/scsi2sd/beta here].<br>
Brief summary of changes:
<ol>
<li>scsi2sd-config and bootloaderhost utilities are gone. They are replaced with a new gui tool "scsi2sd-util". The new tool has many bugs still!</li>
<li>A firmware fix for Samsung-branded SD cards</li>
<li>Support for up to 4 different SCSI ID's, each using a different section of the SD card.</li>
<li>Preliminary CDROM device support. This is still quite buggy, but works on some systems.</li>
</ol>
</li>
</ul>
<br>
</p>
<p>
<strong>[23 Nov 2014]</strong> Price Increase :-(<br>
<strong>For those of you upset over the increase, please keep in mind that SCSI2SD is open source, and you have rights to build, modify, and sell the boards yourself. Everyone else has the right to build the boards and sell them for the original price.</strong><br>
I've had to increase the price of SCSI2SD boards to $125 AUD in order to reduce demand. The price may increase further if strong demand continues.<br><br>
Continued high demand for the boards is leaving me with no time left to work on firmware development. Also, I can no longer rely on "catching up" on orders over the weekend due to high summer temperates in Australia - soldering during 40°C daytime temperatures (104 farenheit) is not pleasant. Soldering during the evening is the only viable solution.

<p>
== Overview ==
<strong>[09 Oct 2014]</strong> [http://www.codesrc.com/files/scsi2sd/v3.6-RC2/ v3.6-RC2] firmware available for testing
SCSI2SD is an emulator for old SCSI hard drives. It allows replacing one or several old broken SCSI drives with a SD memory card.
<ul>
<li>Fix to ensure parity checks are not done when configured with --no-parity</li>
<li>FAutomatically disable parity checks for SASI/SCSI1 hosts, as many such hosts don't support it</li>
<li>Added SCSI disconnect/reconnect support during long SD card writes. This should prevent timeouts on some systems.</li>
</ul>
</p>
<p>The new GUI configuration tool, multiple-device support, and USB mass-storage support is still outstanding.
</p>


<p>
<strong>[03 Sep 2014]</strong> [http://www.codesrc.com/files/scsi2sd/v3.6-RC1/ v3.6-RC1] firmware available for testing
<ul>
<li>Fix additional LUNS showing up on some systems</li>
<li>Improved tolerance of noise and glitches on the SCSI signal lines</li>
</ul>
</p>
<p>I haven't completed any of the promised new features yet. As always, I'm behind schedule. I'm still working on a new GUI configuration tool, multiple-device support (ie. emulating more than one SCSI device), and USB mass-storage support. I'm away on vaction this month, so these features won't be ready until October.

== Overview ==
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.
Traditional hard drives last 5 years<sup>*</sup>. Maybe, if you're luckly, you'll get 10 years of
service from a particular drive. The lubricants wear out, the spindles rust.
SCSI2SD is a modern replacement for failed drives.  It allows the use of vintage
computer hardware long after their mechanical drives fail. The use of micro-SD memory cards
solves the problem of transferring data between the vintage computer and a
modern PC (who still has access to a working floppy drive ?)


<sup>*</sup>All statistics are made up.

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.
