Hm. At an optimistic 5kB per second (via something like the protocol used on 56kb modems), and given a single side of vinyl can be pushed to about 30 minutes, that gives you ~10MB per side. Have you thought about VHS instead? You can fit about 2GB on an E180 tape using the right piece of cutting edge technology: https://en.wikipedia.org/wiki/ArVid https://en.wikipedia.org/wiki/ArVid OTOH, I have just put together a Minix 1.7 distribution which would fit on that vinyl disk, so if downgrading's an option...

  On that note, what's the smallest possible OpenBSD installation?

Biggest offenders: 89M usr 25M usr/libdata/perl5 22M usr/share 12M usr/share/terminfo 5.1M usr/share/zoneinfo 20M usr/lib 13M usr/sbin 9.5M usr/bin You could try removing perl, but that would probably result in a very broken system; the pkg_* tools use it, but also: $ find . -type f -exec head -1 '{}' \; | grep -E '^#.*perl' | wc -l 90

      Hmm. From Minix 1.7: $ du -sh * 144K bin 64K etc 0 fd0 0 fd1 108K minix 0 mnt 0 root 0 tmp 22M usr $ du -sh usr/* 24K usr/ast 3.9M usr/bin 124K usr/doc 0 usr/etc 436K usr/include 1.4M usr/lib 0 usr/local 2.0M usr/man 36K usr/mdec 0 usr/preserve 0 usr/run 0 usr/spool 14M usr/src 0 usr/tmp So if you're willing to lose the source code, you could fit the entire system into about 8MB. Of course, you don't get Perl. Or, uh, TCP/IP networking. You need Minix 2.0 for that, which is much bigger; 26MB with source, or 10MB without.

        A proper comparison would be Minix 3 since it's a real OS. Include just the bare essentials that OpenBSD would include except for reincarnation server it doesn't have. ;)
