Dear Simon and team, My recollection (from 20+ years ago) is that MDI (https://www.materialsdata.com/) had a business in creating new digital interfaces to old analogue instruments, such as the digitization of data from old analogue diffractometers that were originally designed to collected output on a strip chart recorder. It is possible that this problem fits within their expertise.

I have invited them to join the list themselves. Below is their request. We are a solar energy materials group at the Masinde Muliro University of Science and Technology (MMUST) situated in the western part of Nairobi in Kenya. We have a powder diffractometer in our lab that is currently not functioning and we were wondering whether anyone on the list might have some experience and could offer advice or help. The details of the instrument are: Company name: Angstrom advanced Inc. ADX-2700 X-RAY DIFFRACTOMETER MODEL: ADX-2700 SERIAL NUMBER: XTDS-228765 BUILD DATE: 7/2/2015 Basically the issue is it turns on, but Software in the interfaced computer does not communicate with the main XRD machine. The diffractometer turns on well but has never worked since 2017 when it was bought. Since it cannot communicate with the software, it does not work in its current situation in principle. The machine was diagnosed in 2018 with the suggestion that the motherboard may have been damaged by rodents. We do not have any maintenance contract (nor any funds to support one). If anyone has any advice or help to try to get it going we would be very grateful. Simon Billinge on behalf of: Gloria Isendi (Physics PhD Student), Celline Omondi (Physics Lecturer), Miller Shatsala (Physics PhD student), Victor Odari (Physics lecturer), Patrick Tonui (Physics Lecturer), Henry Wafula Barasa (Physics Senior Lecturer), Boniface Ndinya (Associate Professor) Maxwell Mageto (Senior lecturer and Chair Department Physics). PS, we also have a similar issue with an SEM from the same manufacturer in case anyone can help with that too: The SEM turns on well but does not work too. Initially it was diagnosed to lack filaments. -- Simon Billinge Professor, Columbia University
