Japan Board Computer has developed a 10Mb memory board – using 90 1Mbit dynamic RAMs – for use with the IBM Personal AT in both real and protected mode: in real mode, it switches memory banks in 128Kb pages, while in protected mode, up to 10Mb can be addressed directly under Unix, Concurrent DOS 286, and the (not very) forthcoming MS-DOS 5.1 – or up to 16Mb with the maximum two boards; our Japanese correspondent tells us IBM has been testing the $3,700 board in the US for use in the AT.
