They wrote 7MB is impressively small, but they also wrote that it was in 1984. And I guess 7MB in 1984 is likely big... I've heard of computers in the 80s with kilobytes of RAM.
Especially if it's 7MB source code after compressing it into zip.
My first boss told me about his first computer. The entry level model was 4KB of RAM. The upgraded model had 8KB. The salesman looked my boss dead in the eye and said “you’re never going to need 8KB!”
I dont think I owned a computer with more than 2MB RAM until the mid 90s.
in 1983 16kb would have been pretty normal. The Apple Lisa was released in 1983 with 1MB RAM and cost $10k.
