Did 1986 Code allow built-in microwave on one of the 2 GFCI circuits?

The only thing I remember about small appliance branch circuit is that they were allowed, at one time, to supply an exterior receptacle but I don't believe it was ever allowed to supply a built in piece of equipment.

I usually wire the built-in microwave circuit with the 120V outlet for the gas range below. Both would be a separate non-GFI circuit from the two SABC's (which are GFI). Not sure about local codes in your area, but inspectors have always allowed me to do that at any house I've ever worked on.

Back editions of the NEC to like 1968 IIRC can be viewed for free at the NFPA website.

The only outlets allowed to be supplied by the 2 SABC's besides the countertop outlets were an outside receptacle as Dennis said, and a clock receptacle. From the 1984 NEC.

I remember we used to label the separate circuit "Radarange"

When I started in this trade was using 1987 NEC, pretty certain the outside receptacle wasn't allowed on SABC then, clock or gas range was, and fairly certain that like today outlets in dining room, pantry, breakfast room, or similar rooms were also required to be on SABC's.
The GFCI requirements in 1987 were only for those receptacles within 6 feet of the sink. I think it switched to all kitchen countertop receptacles in either 1993 or 1996.

Was this the 60s by chance?

did the code really need to say that , what about the section that does not allow a appliance fastened in place to not exceed 50%

Actually, it was in the late 70's...
... I had forgotten about the slang term "Radarange" until I recently worked in a home I wired in the 70's and saw the panel labeled. I think they were referred to as "Microwaves" by the late 70's, but the slang term "Radarange" was still used. It's really strange when you go on a service call and you look at the panel labeling and you notice your own hand writing on the panel cover...from a job you did over 35 years ago. I say to myself...OMG I wired this place.

Technically its not slang, well, at least is was the Band-aid and Kleenex marketing of the day.

That will keep the 12 amp fastened in place appliance from going on any 15 or 20 amp circuit.
In the 1980's you were seeing over the range "fastened in place" microwave/hood units. But a microwave sitting on a cabinet shelf is not fastened in place - yet has never really been allowed on the SABC's unless, and somewhat of a big maybe, it somehow works out that it's receptacle is considered to be serving the countertop.

Radarange was an Amana trademark and they were still being sold at least into the early '80s. We got one when we got married in '83.

If I am correct its a Raytheon trademark, or at least Amana was. The Amana name today is owned by Whirlpool corporation, but sadly no radarange name. I've always thought it was cool name.

OK, I wasn't necessarily clear with what I said, this rule does force it to be either an individual circuit or to only supply other fastened in place appliances, doesn't matter if it is in the areas served by SABC's or not.

And outdoor receptacle was still an allowable exception in the 1990 code. It was gone by 1999. I don't have my '93 or '96 books handy.

Now you are going to make me get out old book and look. I didn't think we were ever allowed to put anything outside the kitchen, pantry, etc. on a SABC since I started this trade - using 1987 NEC at the time.
220-4(b) 1987 NEC, exception 2: outdoor receptacles.
guess they were permitted, I don't ever recall installing them that way.
My home built in '97 has an outdoor on the sabc. I'm not sure which code cycle we were on at the time.
