- stephengillie 8y agoThey must have needed huge batteries - or could the bus engine power a large enough inverter to power all the 486s?
- owenversteeg 8y agoMy guess would be a big gas generator in the back of the bus.
- gsich 8y agowhy an inverter? I don't think DC-AC-DC is more efficient then DC-DC.
- stephengillie 8y agoThe bus alternator produces up to 80 amps at 20 volts - while the computer needs 12, 5, and 3.3 volts, in the 1-20 amp range. Using a common inverter and a common power supply is the cheapest way to convert the voltage.
- chrisdhoover 8y agoBus altenator is 24VDC? Plus charging voltage so a 27.6v output?

- weinzierl 8y agoThen it couldn‘t possibly have been in the 1980s. The 80486 didn‘t exist back then. The 80386 exists since the mid 80s but would have been very expensive.
- Animats 8y agoThe original CMU Navlab was like that. Three racks of Sun workstation in the back of a van, and a generator to provide power.[1] By the early 1990s, they had one that more or less worked, a Pontiac Firebird with self-driving comparable to Tesla's today.
