Hey where's RTL? 914's, 923's etc etc
Sure I'm familliar with the concept, but only from
an overview standpoint. Just what is it with DTL vs
TTL anyway? Why didn't they use TTL from the
start? Was it a eureka genius thing or did it take
advanced transistors to make it possible?
A quick answer would suffice, we got too much
bandwith as it is.
I suspect TTL was harder to fabricate
There was non-integrated RTL and DTL logic before ICs not sure about non
integrated TTL...

This question for me dates back to the early 80's
