The EU is a variant of that used on the F-16A/B system The EU 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 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; this later version has a memory of 32k.
The EU has a marking.PT No. 229-045138. The LVPSU is Pt. No. 7506-00071 Ser. No. 021, AC-001-001-03
