Product Description
The DEC SQ706, also known as the Dilog SQ706, is a specialized controller card designed for Digital Equipment Corporation's Q-bus computer systems. The Q-bus was a popular architecture used in DEC's PDP-11 and early VAX minicomputers. This controller card is specifically identified as a disk controller, meaning its primary function is to manage and interface with storage devices, such as hard drives or other mass storage media, within the Q-bus environment. The 'dual-height' designation refers to its physical form factor, indicating it occupies two standard slots on the Q-bus backplane. This was a common size for more complex peripheral cards in that era. As a disk controller, the SQ706 would handle the low-level commands required to read from and write to storage media, translating them into signals that the drives could understand and vice versa. It would also manage data flow and potentially provide error checking mechanisms. This card is a component of the Dilog product line, which was a significant third-party manufacturer of peripherals and expansion boards for DEC systems. The SQ706 represents a piece of legacy hardware essential for maintaining or expanding the functionality of older DEC computing systems that relied on the Q-bus architecture for their storage subsystems.
