QSR Automations Inc produce a range of 'Kitchen Display Controllers':
QSR has led the industry for over 25 years in providing reliable and flexible kitchen display controllers. Whether you operate table service, quick service, fast-casual, bar, concession, or pizza restaurant concepts, we have hardware and an operating system to match.
Anyway it is a packaged PC sold into a niche market place in a similar manner to a thin client hence my purchase of one. I also note that QSR now include the HP t640 thin client as part of their hardware range.
The QSR eXpert DX-3000 occasionally appears on eBay but is usually outside my price range. However one recently popped up which was described as untested due to the lack of a PSU and my (low) offer for it was accepted.
Possibly because it is a niche market area Google didn't find much about the DX-3000. It was not helped by QSR's website having no historical data and their support pages essentially being 'contact support'. When I bought the DX-3000 I had no idea what CPU was fitted. From a few eBay listings where the seller included a photograph of the unit label I could see:
Manufacturing Date | Flash | Memory | OS |
---|---|---|---|
Jan 2015 | mSATA | 2GB | WES-7 |
Jul 2015 | MicroSD | 2GB | WES-7 |
Mar 2016 | mSATA | 2GB | WES-7 |
Apr 2016 | mSATA | 2GB | WES-7 |
Nov 2019 | 32GB mSATA | 4GB | Win10 IoT |
Oct 2020 | 32GB mSATA | 4GB | Win10 IoT |
Sep 2021 | 32GB mSATA | 4GB | Win10 IoT |
So it looks like it was launched 2014/2015 and at some point the embedded OS switched from WES7 to Win10 IoT. I did find a distributor's document showing that the DX-3000 was discontinued by August 2022.
My single example is the one manufactured in July 2015. Whether the internal hardware has been upgraded/changed between then and August 2022 I have no idea.

The embedded OS was WES-7.
Later models running Win10 IoT
Mine came without a power supply but from other eBay listings I determined that the standard PSU
is a 9V 2A supply with a 3-pin DIN locking connector.
A PSU label is shown right.
The DX-3000 is fitted with a single core 1GHz AMD G-T40R CPU.

As usual, clicking on the photo (right) will take you to a larger scale photo of the circuit board.
Flash: The board is fitted with a microSD card slot and an mSATA socket. The mSATA socket is rather restrictive as it only takes the 'mini' size (26.8mm x 30mm) mSATA board. In my experience that size of mSATA board are more difficult to track down and are, as a consequence, more expensive than their larger counterparts.
RAM: The RAM is a conventional DDR3 SODIMM plugged into a socket. The fitted 204-pin SODIMM was a 2GB Crucial part. I tried out a Crucial DDR3 8GB part and an 8GB SK Hynix DDR3-L part. Both worked.
The AMD data sheet says 'DDR3-1066 unbuffered'.
USB: There are three USB 2.0 sockets, two on the front panel and one socket on the rear.
Serial: There is a single 9-pin serial port on the rear panel.
There is a movable link.
There is a small slide switch which appears to be in the 'off' position.
There is a 2 x 5pin header. I assume that this is a serial console supported by coreboot. If it is then the standard layout is:
