Because people worked hard to do it. You also used a lot of frowned upon patterns. You bit twiddled. Today you use a guid, a 128 bit number, in string format, as an id. Back then you used as few bits as possible, as bits. As computers got faster and has more memory. We used better techniques, to make our code now robust and do more things. But we also lost sight is the premature optimization. Some of it would do no good today. Today it isn't usually with trying to trim a few extra megabytes... Back then you worried about every bit Guess, there are trucks. But the majority of them works probably get you fired if you tried to use them today.
