Being an essential component of a flight system also meant the military pushed for safety and failsafe measures. That was tricky, with such a cutting-edge development in a new industry. What ended up being provided to the F-14 Tomcats was a system that could constantly self-diagnose issues while executing its flight computer duties. These MP944 systems could apparently switch to an identical backup unit, fitted as standard, within 1/18 th of a second of a fault being flagged by the self-test system.
As mentioned above, this processor of many firsts seems to be of largely academic interest nowadays. However, if Holt’s attempts to publish the research paper outlining the architecture of the F-14’s MP944-powered CADC system had been cleared back in 1971, we’d surely now all be living in a different future.

USAFRet OK, we (myself included) are starting to stray into 'politics'. Let's not do that, OK? Reply
Crotus of Borg Of course humans always have to apply the best technology to kill each other first. One only has to look at this example to know that we are very doomed in this world of advanced tech. Just imagine what governments are hiding from us today. It was nice knowing you all. Reply

shady28 Makes you wonder what's in the latest and greatest. I especially wonder about the F-22, there were multiple overt requests by Japan, Israel, and Australia to buy them. Congress explicitly banned it from export by law in 1998. 🤔 Reply

hwertz Are you joking? They are just moving away from using like 8" floppy disks etc. to update these things. I can guarantee there isn't remote update anything in them. If for no other reason simply because the development timeline probably means a jet out now would have started development in the 1990s, and over the air updates (and the associated risks) weren't a thing then, you'll be lucky if it has a USB port as opposed to just using the 'newer' 3.5" floppies or CD-ROM or something.
