Most consumer cameras from that era that weren't spot metering used a center-weighted averaging meter pattern that took up roughly two thirds of the screen with the emphasis on the center of the screen first and, to a lesser degree, the bottom of the screen.
Minolta SRT's used their CLC system that biased the reading toward the bottom, reducing the tendency to underexpose.
If you need to know the precise metering area and don't want the A series cough that's caused by the mirror braking mechanism I suggest you buy an F1 or FTb they are also both all metal, better made, and more reliable cameras than the AL1.

Some of the A series Canon SLR's can also have a problem with a cover over the metering cell. Apparently it can go cloudy over time.
I don't know if this can be cleaned or if the cloudiness goes right through the material. I have my doubts that new replacements are
still available. Perhaps the cover could be removed during a CLA.
I found this out recently when my AE-1 was overexposing by 2 stops. I also checked my A-1 against a Canon EF, an F1-N and a T90 and it
was overexposing by 1 stop compared to the other three bodies. My A series bodies are both in exc condition and were last serviced
within the last 10 years. No mirror squeak. For the time being I'll just compensate via the film speed dial. I like using the A series bodies from
time to time as they are a lot lighter than my other FD's.
The AT-1 is mistakenly overlooked, because it emerged in a period when automatic exposure was a must-have accessory. It wasn't even available on the Japanese domestic market, but was aimed at emerging countries where the extra price of auto was a deal breaker.
I also heard this camera was intended for the North American market. As a matter of fact, I got hold of one of these in mint condition for some 20$... And it works perfect. I consider this camera as a perfect camera replacement and much less expensive than the A-1 or AE-1 ones. A real underestimated camera.
