The F-16 Electronics Unit was based on a powerful general purpose computer using MSI TTL technology. It contains a MIL-STD-1553 data bus interface, processor and symbol generator. Data can be received in analogue form but the digital Databus significantly reduces the number of data lines. With progressively smaller airframes finding space for the traditional bundles of analogue cables and their bulky connectors was becoming a problem so the new system links HUD, attack radar, fire control computer and the inertial navigation system all through the 1553 data-bus. Development of small RISC processors had continued within ADD and FARL and the F-16A/B emerged with a solid state 16K 16-bit store in what was basically a 12/16 RISC implementation. Eventually the memory was increased to 32k.
The Electronics Unit is fitted with an ELDEC Power Supply Unit slab, type: 4-174-02, Ser No: 104.
