sixteen DIP sockets accept 0.5, 1 or 2 MB RAM
supports 256k×4 (44256) chips, 120 ns or faster
cannot use DMA to transfer data to 32 bit fast RAM
if Zorro II DMA memory is not available the driver falls back to programmed I/O transfers
performs extremely slow in the A4000 because of the above mentioned two problems
