A wired chassis without circuit boards and power supply.
It is fitted with a cooling fan rather than relying on cooling air from the aircraft.
This is the first production Electronics Unit from the HUD system fitted to the C-130 Gunship. It is a wired chassis without circuit boards and power supply. The EU Processor/Symbol Generator uses the MIL-STD 1553B (Standardised Electronic Data Highway) databus architecture, the MIL-STD-1750 (Standardised Computer architecture) processor and the MIL-STD-1589A (Standardised Jovial J73 Computer language) software. This was the first time that all three Standards had been used together and the Company was way ahead of its US rivals in this respect. The foundations for the implementation of these Standards was laid down by FARL from 1978 and led to a highly successful LSI chipset for the 1553 Databus. The HUD EU has comprehensive video mixing and scan conversion and self-contained weapon aiming capability.
