This is a very compact QIC unit. It uses a full-sized QIC tapes, but it's more compact than original Tandberg units. It lacks a joint mechanism which made Tandbergs unreliable after few years of regular tape swapping. On the other hand, it's a very early QIC unit, so it can work only with QIC-24 45MB tapes. Again, it's very compact and it has all locks preventing user from putting inside things other than QIC cartrigde. The door is electromagnetically locked and unlocked only by software. Connector is not default pin SCSI, but a strange 50-pin edge connector.
