I've been using this PCMCIA SD-card reader on both my A600 and A1200, and it has worked like a charm. And my micro-SD cards came with an SD-adapter, so they work fine too.
I've got the same adapter and I'd like to use on my A1200, but... I don't remember how A1200 reads it!
I tried with prepcard bud it says the card is write protect.
How A1200 reads the memory cards through pcmcia?
