Any good old book for bipolar circuit design with only NPNs ???

Does anybody has a good reference for circuit design with only NPN transistors??
I know many years ago only NPN were available, so there must be one of those old books that has been forgotten or lost in time....

That would have to be -really- old, because before 1980
there were complementary bipolar technologies and National
was using laterals in their op amps and comparators in the
'70s. And those guys didn't have IC design textbooks, they
cut their own trail.

But perhaps the most immediately instructive thing you can
find, is an old fat National linear databook from back when
men were men and they published their schematics.

Earlier Gray & Meyer editions were almost all bipolar based,
though not NPN-only. Dealing with NPN-only is really more
about a "bag of tricks" than theory anway, which brings me
back to the databook-scrounging suggestion.

Old, "high speed" comparators and op amps in technologies
that had only lateral PNPs, are naturally going to use NPNs
for the signal path almost exclusively, so should be most
instructive.

Currently, I am at National!!!
Yes I do have a full set of old databooks.... I kept them because of the schematics.....
The situation is I have a GaAs NPN only process.... no PNP anywhere or allowed.
So creating a sourcing current source is a problem...... trying to avoid resistors.
level shifters not a problem.....
sinking current is not....
