This board uses a non volatile static ram and a Xilinx complex programmable logic device to emulate up to 4 DF32 disks drives. The transistors convert between the -3V logic of the negative bus DF32 and TTL logic levels. The boards plug into where the cables to a DS32 would normally plug in. More information
