v7x86-0.8a.iso - ~14.6 MB
Keep in mind, that also includes kernel, kernel source, C compiler, C compiler source, and utilities and utility source.
For comparison, the source of most recent version of gcc, 10.2 -- gcc-releases-gcc-10.2.0.tar.gz -- weighs in at ~118.7 MB, and that's compressed...
Or for comparison, one of the "standard" 600 MB+ (and sometimes much more!) Linux distributions...
Also, v7 Unix occupies a unique place amoung Unices, that is, it's
the simplest possible version of Unix that is actually still functional with the code being readable
(earlier versions have much more assembler code and less C) -- so anyone interested in learning Unix or one of its derivatives from the ground up is well advised to study this source code!
To the Author: You undertook a great job in getting this ancient code base to work on x86, and the community of Unix researchers, students and scholars, both now and in the future -- thank you for this laudable effort!
