What are the best classic cars that won't break the bank, are easy to maintain, have good gas mileage, don't have a computer, and are good for driving in dry, wet, snow, and ice?
If you don't want any computers at all you're looking for the most part at pre-1980 vehicles. Assuming you are in the U.S., from the standpoint of parts availability and serviceability cars from the domestic "Big 3" manufacturers would be best. Keeping rust at bay will be a problem if you plan to drive on winter salted roads. Also be aware that unless you know a mechanic willing to work on cars that old (relatively few) you will need to work on it yourself.

That kind of a car doesn't exist. Carburetors are pretty inefficient devices, especially compared to a more modern fuel injected engine.
2-door and 4-door Ford Escorts from the early '80s MIGHT work if you want a fuel injected engine, but any car that age is WELL past its prime, not to mention potential rust issues, etc.
I have a 1979 Pontiac Catalina, and I'll drive it when it's not snowing, sometimes 3 days a week. It's my project and I have two other cars. It's not my daily driver by any means. Don't rely on some ancient car to get you from place to place as a daily driver, especially if you don't have working knowledge of cars. Almost no mechanic works on cars old enough to have no computers. You probably need to go to somebody who specializes in old cars, which will cost a lot more money if you can't fix stuff yourself.
I had to school a professional mechanic we use when I can't fix something. The rear main seal in that car went out and I had to nurse the engine back home; I went through 6 quarts of oil in 26 miles! The mechanic didn't return my car for three weeks. Everything else I've done to that car, I've performed myself. I have the GM factory service manual on CD.
Computers in cars were designed to overcome shortfalls, and they're not all bad. It was snowing a few years ago and I was driving my 2017 Mustang. The roads were covered in snow, it was the middle of the night, and I tried my hand at driving the car manually. I couldn't get going without computer assistance and I just spun my wheels.
Maybe something like this 1949 Studebaker Champion would do the trick. Seller claims he drives it to work every day.

Although not a "Big 3" product, parts and support for Studebakers are actually pretty decent.
