For notes going on about NetBSD 0.9, which was released around August 20th, 1993.
From the source code NetBSD 0.9 supported the following platforms:
- VAX (while not in the source I've been able to find, I've heard from Johnny Billquist about running 0.9 on a VAX 11/750.
Now that I found one, I guess ill have more 'significant notes'.
for now I've simply mirrored the install directory on my server....
I should also add I've had disk geometry errors with Bochs, and DMA and no ide detection under virtual box.. Virtual PC seems to just hang at the hard disk... However VMWare Fusion 3.1.1 on OS X works great!
This is from the generic kernel

I've found this configuration good for QEMU (which can run NetBSD 0.9 once it's installed)..

getting this to run
I've built a disk image with VMWare, and converted it to something Qemu can run. You can download it here. I had to make a modification to Qemu 0.13, regarding the NE2000, as the first instance in hw/pc.c is setup for 0x300, IRQ 9 there is an IRQ conflict, and Qemu won't start, so by simply removing the first definition, Qemu / NetBSD can run under Qemu with the NE2000 configured for 0x320 IRQ 10 .
For Windows users there is a pre-built exe in the zip file.

NetBSD 0.9 seems somewhat robust, the largest problem seems to be something with stdlib... Also modifying machdep.c you can easily use 172MB of ram, more seems to cause weird crashes...
