The RK8-E disk controller was the PDP-8 OMNIBUS disk device controller for the RK05 disk drive. A single RK8-E could handle up to four RK05 drives. It used the single cycle data break form of DMA to transfer data directly to main memory. It uses blocks of 256 words; data transfers can range from 128 words up. It uses a CRC for data error detection.

Hardware

The quad boards which made up the RK8E were the M7104, M7105 and M7106; they plug into an OMNIBUS backplane.
