the beauty of written content, you can skim the whole text in a few seconds, see if it interests you, jump to the conclusion, go back and read it all... in a world that's turning completely to video content, I'd say we can forgo the supposedly not so good style.
OTOH, he doesn't seem to really answer the real question: why they still used TTL when much more highly integrated CMOS technology was already available in consumer market? I guess it's something very specific to aerospace strict standards, and as far as I can tell he didn't say much about it.
- rlaanemets 6y agoAren't older TTL more resistant to radiation because of physically large chip structures? It could be that those chips were already space-tested or radiation-hardened.
- aulin 6y agoyeah, I believe it should be something like that. Anyways I think the author created some anticipation of giving an explanation about the reason of all those chips and the conclusion was just something like "there are many ICs because it uses TTL and each TTL IC doesn't do much so you need many of them". Ok... but why does it use TTL? that's the interesting question, isn't it?
