Is a demo disk available for the PC?  If so, how does one get it?

I'm happy to hear about it. That makes my life easier. So I'll make yours too,
by posting on Friday (i.e. as soon as I've finished the documentation) my
mkboot package for the Atari. (I dropped gather2. Can't find the damned bug.
I'll rewrite it from scratch next week). Basically, it will removes the need of
a special disk with with a filesystem part (the RAMIMAGE copy) and a minix
image part. With mkboot, you make a Minix Filesystem floppy bootable (Such a
disk loads the /minix.img file from disk and starts it). You just add
rm /minix.img to the /etc/rc script to recover ~80K on your ram disk,
and here's a stand-alone Minix disk!

If you look at the code, you'll find some #define intended for demo versions.
I think there was one for 1.3, so there should be one for 1.5 too...

I haven't finished it yet.  When it is done, P-H will probably sell it
for roughly $10.  They actually wanted to give it away free, but I warned
them against that.  When I offered a free book on Amoeba a couple of
months ago, I got 1000 responses in the first 3 days :-) + :-(

 ^^^^^^^^^^^^^^^^^^^^^^^

That presumes that one already has Minix.  I thought that the purpose
of a demo version was "try before you buy".  Its kind of hard to look
at the source code of something you don't have.;-)
