Long shot but does anyone have a Smart Media card they want to get rid of to someone who will use it?
Smart Media was a digital storage format for early consumer digital cameras in the mid-late 1990s that quickly became obsolete around 2001 as Compact Flash and SD dominated. They were very thin which possibly limited their capacity, which was in turn the death knell, really - I think they maxed out at 128Mb.
I recently purchased a quirky little 1999 camera, the Sharp VN-EZ1(*), which uses these cards. There was no card with it so I have spent £18 (!) on a 128Mb one, and it comes up as "Card Error" on the camera. It is seen perfectly fine on my Mac and Windows computers via a card reader, there were someone's old photos on it, I deleted those and then tried reformatting the card to, well, everything. exFAT, NTFS etc. No joy in camera. And I can't see a way to format in-camera partly because all the menus are stuck in an Oriental language! I wonder if the camera can't handle a 128Mb card (specification says "up to 32Mb") but at this stage I am loath to throw more money at this thing.... just interested to see if a lower capacity card might work
* amazingly, Sharp's website still hosts what must be the original pages for this camera. Relish that font, layout, and concern over users not being able to play back video files ...and in fact explaining why digital video files are nice and interesting things! https://global.sharp/inet-viewcam/text/features.html
