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. 229-05138 and ‘China programme’. The LVPSU is Pt. No. 7506-00071 Ser. No. 021, AC-001-001-03

In August 1980 the Company’s Airborne Display Division (ADD) received an order worth £40million from China National Aero-Technology Import and Export Corporation (CATIC) for the supply of Head Up Display equipment, trials and licensed manufacture in China. The J-7 is a version of the Soviet MiG-21 fighter/interceptor aircraft built in the People's Republic of China, with a number of improvements. It is also commonly known by its export designation of F-7. The J-7IIA, which first flew in March 1984, saw additional changes in the form of improved avionics based on Western technologies. These included the Company’s Type 956 HUDWAC which became standard for J-7 fighters from then on. Around 436 HUDs of this type were made.
