I am working with others to archive some computer related documents.
I added your link to my favorites and will look at it when I get a chance.
Too many olders docs are just considered that - older docs, and are thrown
away. Later when you want or need them they are not available.

Subject: Re: RTL Logic
It would be
great to have an online source for RTL specs, like most
people I have no RTL docs.
But there are many RTL families, and only some are compatible. RTL
isn't a brand name, it means only "resistor-transistor logic". TTL
is also quite accurately described as "resistor-transistor logic",
"branding" was done there certainly to distinguish, and today,
nearly all "TTL" families died off except the TI 74xx stuff, but
you can't extrapolate backwards.
(I don't mean to start a pissing match over meanings of acronyms
(TTL, RTL, DTL, etc), I speak loosely to warn about not taking
names too seriously.)
I have some few datasheets for early logic families here:
