the board is basically the combination of the A.L.F. IDE controller and the MemoryMaster memory expansion cards
uses polled I/O, not DMA transfer
RDB compatible
40 pin internal IDE header
place for a 3.5″ hard disk on the card
delivered with A.L.F. 2 driver software
during transfers the high and low bytes are swapped as the A600/A1200/A4000 and PCs do so the drives formatted with them can be handled by the AT-Bus 2008
hard disk activity LED connector
