I had a short look on the ringworm. It seems to be more complicated than I could handle plus I cannot believe that it is economic. EFN does not list them but I already sent Ulf a mail. (…partly deleted again for being unnecessary emotional…)
I know that there will be some kind of “solution” that will make this thing working - I am just disappointed. This is a module that is marketed as fitting in an existing framework and I expected it to physically fit there without digging into private PCB production (yes, I know - no acid tubs). At the very least it would have been nice when this necessary accessory would have been clearly mentioned when buying it from the shop.
I would not have thought something like that, remembering the slight smile that cam over my face when I opened the teletype box and found that it came with three header to mount on the trilogy modules for i2c connection. That thoughtfulness made a large impression on me.
