There have been a lot of talks in recent years about DB19 connectors. Even though these connectors are obsolete – or at least considered as such by certain computer experts – they have been making a comeback as people try to continue using their older computers in order to run dedicated pieces of software that can’t easily run on newer machines.
DB19 connectors feature 19 pins (10 on the first row and 9 on the second), arranged similarly to the pins on most VGA cable connectors. Before they were dubbed as obsolete, they were used extensively to connect old computer screens and external hard drives, and they were also used quite frequently for ASCI connections on old Atari devices. The reason DB19 connectors are still used today is primarily because access to such devices is still required, and secondarily because the older the device, the easier it is for connectors to break or become damaged in some way.
While individual pins on a DB19 connector are hardly ever replaced, the connector itself as a whole is easy to replace, so that action is performed quite frequently. As a result, high DB19 demand has led to an increasing number of manufacturers producing these connectors, so if you need to make use of them, it can be quite cheap and practical to buy one from your local electronics store or order them by the dozen online.
