Big photo session taking high-res photos of each and every circuit board in a #Siemens EWSD #ISDN switch yesterday. Will all go to the #retronetworking wiki after editing.
edited circuit board photographs of each #Siemens EWSD #ISDN switch circuit board in our collection now in the #osmocom #retronetworking wiki below https://osmocom.org/projects/retronetworking/wiki/EWSD_Components - now we "just" need to add description texts and metadata like part numbers, cross-references, etc.
@mnt an EWSD telephone exchange contains hundreds of boards in dozens of component carriers and >= 3 racks full of component carriers. Not every board needs to contain a CPU, though many do.
