The very interesting thing about RTL was that the
ICs could be
operated in the linear region for lots of non-logic applications.
Now that is something I didn't know and find very much worth looking
into. Any quick pointers to info on RTL operating in this mode?
Don't know about anything online, but in print keep your eye out for a copy of
Don Lancaster's "RTL Cookbook" (Sams, 1969), the predecessor to his better
known "TTL Cookbook". There's a chapter on "Linear Circuits and
Mostly it's just biasing an inverter into the linear region with a resistor
to + on the input, but one of the cute tricks is to take two inverters in the
same package, raise the GND pin (common emitter) above circuit GND with a
resistor and so make a differential amplifier
(...on the other hand, the 709 was around at that time...)

I'll dig through my old literature. I recall that
an "Experimenter's Kit" of about 6 of their TO-99 packaged milliwatt
RTL circuits with some non-digital application notes.
Anyone still have the little booklet that came with
Bubble pack on mauve-colored cardboard backing?
"Motorola HEP Integrated Circuit Experimenter Kit"
"5 Prime Quality RTL I/C's"
I have two unopened packs, the staple holes are present in the cardboard where
presumably the booklet was attached, but the booklet is gone.
