Huh! You noticed them just a little sooner than I did. Reading betweent he 
lines of the README, it looks like they were being very careful about MBR 
matters. I think a hard disk image with an empty MBR should be enough.

I stand corrected.

I think I have images of those, could send them if desired. At least, the ones 
I have are described like this in the README:

They also contain fixes, perhaps over the iso? Anyway, if they contain iso9660, 
I imagine they're enough to get the iso installed.

These will probably work, except acme hadn't been invented yet and
sam may or may not give an error the first time. (Checked with
another demo disk.) You probably do want to start the window
system, there is no way to kill the foreground process without it.


Acme (Alef version) is in 2ed; the single-floppy version doesn't seem 
to have the binary. Looking at the screenshot that Will sent me 
directly, the dates on the binaries match up to 2ed release.


I'm pretty sure the four-floppy set that came with the CDROM has the 
acme binary. I don't have any floppy drives that I trust to look at my 
copy.

Interestingly enough, I found an old 4 floppy set of vd's in the same 
folder with the demo image. It looks like they are Nov 1995 (I 
apparently winimaged them from floppies back then). When I boot disk 1, 
it complains about not having an mbr partition and bails. I'm guessing 
it's expecting some OS and hard disk to be present to install to.

Acme (Alef version) is in 2ed; the single-floppy version doesn't seem to
have the binary. Looking at the screenshot that Will sent me directly, the
dates on the binaries match up to 2ed release.

I'm pretty sure the four-floppy set that came with the CDROM has the acme
binary. I don't have any floppy drives that I trust to look at my copy.

These will probably work, except acme hadn't been invented yet and sam may or 
may not give an error the first time. (Checked with another demo disk.) You 
probably do want to start the window system, there is no way to kill the 
foreground process without it.

I could email a slightly newer demo disk which prompts, "Start the window 
system? (y/n)". Note that it has more annoyances than 4th edition. For 
instance, while the down arrow key behaves appropriately, the up arrow key 
inserts Î. Home inserts Í, End inserts CR. Double-click doesn't select anything 
in 8½, which is a nuisance when you habitually use send. The grep command does 
not exist! It does, however, have ftpfs. Useful demo, not useful tool.

I could email a 2nd edition CD-ROM too. It has grep and the source to 
everything, but it's not a bootable disk. I don't think the demo floppy's 
kernel has appropriate drivers. (It certainly lacks 9660srv.) The contents of 
#S are unfamiliar too. The demo floppy lacks a lot of things, such as 
/dev/drivers and even ns, which hinders exploration. I extracted a bunch of 
kernels from the CD-ROM in the past, but I couldn't be bothered to figure out 
how to boot them, much less find which one(s) will mount root from a CD-ROM. I 
wonder if they'll boot if I tell qemu they're floppy disk images... (tired now)

Re: [9fans] Early version of Floppy Demo

[will . senn]

I figured out how to get the graphical system to work... when it asks about the 
mouse, select a valid option :) - ps2, 0, or 1...

Now, I just need to figure out which mouse options to set in 86box, so the 
mouse actually works!

Going by memory, assuming aux/vga ran, you should be able to type 8-Alt-1-2
to type 8½
You should also be able to start acme or sam instead of 8½.
