I have also tried a cheap card reader, with a SD card formatted as FAT32, and it still doesnāt work. Iām giving up (again). Maybe Compact Flash are supposed to work, and SD not? This is very strange. But right now I canāt be bothered buying another adapter for a CF card, just to find out it doesnāt work either.
I wonder if changing the āallocation unit sizeā, when formating the memory card as FAT32, will make any difference. But without a PC at home, itās going to take me a while to go through all the different sizes available, to see if that makes any difference to Teletype.
