The original Albireo card was created by PulkoMandy, it offers mass storage (USB and SD card) and a serial port. It is nice to be used with the Unidos ROM (Futurs). Zik (Futurs) has obtained the agreement of PulkoMandy to create a v2.0 of the Albireo card without the serial port, and already two batches of the card have been sold. But to make a third batch, 20 to 25 orders are needed. So don't hesitate to torder one as the price of 25 euros is peanuts for the features.
