According to "Apple Technical Specifications: Legacy Products",
http://www.info.apple.com/support/applespec.legacy/index.html
there are 34 kind of fpu-less '030 Macs.

I sent "List of FPU-less '030 Macintosh" and my config file to Bruce
including some options for NetDock and Cabletron AE41*.
I hope new kernel will support all of those 34 Macs and thier
networking devices.

To decrease kernel size is also important because some '030s have
small amount of RAM.

Please correct and modify that config file with your idea. I'm not sure
about some options, and I think that you and the members might have
better idea for the new config file.

>Let's call it something other than SMALLRAM. That might be easiest.

Yes, that's a good idea.

The installation "Prebuilt NetBSD 1.6.1 for LC040 Macs" binary sets
http://edoneel.chaosnet.org/Downloads.html
is going on my LCIII+ now.

Macintosh LC III+
http://docs.info.apple.com/article.html?artnum=112229
030/33MHz, 36 MB RAM, 768K VRAM  512 x 384  16-bit
NetBSD 1.6.1 (GENERICSBC) was running nicely on it with FPU.

I pulled out the fpu chip and tried to run 1.6.1 "netbsd-INSTALLSBC.gz",
but it got;

>status: failed: command ended on signal

Do you have any instkernel for for LC040 Macs?
I can't access to:
pub/NetBSD/NetBSD-1.6.1/mac68k-softfloat on lilith.sixgirls.org

I have another "netbsd-INSTALLSBC.gz" which is 1.6G SEP 2002, made
by Takeshi Shibagaki for fpu-less Macs. It works excellently on LCIII+.

-------------------------------------------------

I've just finished to install all binaries including X set.
While the additional installation and some basic settings, I don't see
any error nor any strange thing.
Your "Prebuilt NetBSD 1.6.1 for LC040 Macs" runs greatly on LCIII+
without FPU.

I compared the time (performance) with IIci;
lc3+: {1} time /etc/rc.d/sshd start
Starting sshd.
1869.6u 1.7s 31:35.52 98.7% 0+0k 4+36io 46pf+0w

IIci: {1} time /etc/rc.d/sshd start
Starting sshd.
2531.3u 2.5s 42:52.26 98.5% 0+0k 3+35io 44pf+0w

FPU-less LCIII+ is much faster than IIci (25MHz, 20MB RAM, with FPU)
in this case. (It doesn't use FPE?)
Now I know "FPU-less" doesn't mean "slow" in some case.

Thanks for your advice.

Wonderful !  I don't see any error. I think it is already good enough for
many FPU-less '030s, and it will be perfect with a few network device
support and decreasing kernel size.

Hi,
Thanks for your post :)
Bruce's Color x is also great on my LCIII+. It runs at 512 by 384, 16 bpp.

Very interesting. What config file do you use? Would you like to tell me (us)
your config file?
