OpenBSD's source tree just turned 20 years old. I recall the import taking about 3 hours on an EISA-bus 486 with two ESDI drives. There was an import attempt a few days earlier, but it failed due to insufficient space. It took some time to repartition the machine. It wasn't terribly long before David Miller, Chuck Cranor and Niklas Hallqvist were commiting... then more people showed up. The first developments were improvements to 32-bit sparc. Chuck and I also worked on setting up the first 'anoncvs' to make sure noone was ever cut out from 'the language of diffs' again. I guess that was the precursor for the github concept these days :-). People forget, but even FSF was a walled garden at the time -- throwing tar files with vague logs over the wall every couple months. I was lucky to have one of the few 64Kbit ISDN links in town, otherwise this would not have happened. My desktop was a Sparcstation 10; the third machine I had was a very slow 386. The project is now at: ~322,000 commits ~44 commits/day average ~356 hackers through the years
I thought I’d try OpenBSD 2.0 SPARC on Qemu! Â Well either with SUN PROMs, or OpenBIOS the result is the same, it crashes when initializing the SCSI bus.

But you can play kernel hangman, if you are into that kind of thing.
But make no mistake, the new 5.8 release (just released!) boots up just fine on Qemu:

Welcome to the OpenBSD/sparc 5.8 installation program.
(I)nstall, (U)pgrade, (A)utoinstall or (S)hell?
Just don’t bother with the ‘install diskette’ try the miniroot instead.
