Just read it, or copy the entire CD to /dev/null and see if there are any
read errors reported.

Most can. Some *only* do that!

If you make the RT-11 part as some sort of container file (LD: volume?),
you can use mkisofs to build an image consisting of everything else, and
work out its size. Then burn a CD which has two (or more) tracks: first
the ISO-9660 part (possibly with Rock Ridge and/or Joliet extensions), then
the container (or put some padding between to make the start of the
container where you want). Or start with the container, though I'm not
sure if that necessarily means it would start at a specific block. I'm
also not sure how many systems can read a multi-track data CD.
The way people usually do it for EFS disks for IRIX (EFS is the native
SGI/IRIX filesystem format used for bootable installation CDs) which have
to have partitions, is to build the image on a hard drive first, and burn a
raw copy of the entire hard drive (rather than the files/filesystem on it).

wget on a unix or Linux system. You'd want to pick your root point and
start wget with the -r (--recursive) and -k (or --convert-links) options
(to make any absolute links into relative ones, wherever possible) and the
-np (or --no-parent) so it doesn't follow links that go *up* the directory
tree rather than down (a good way to get lots more than you intended!).
There's also a -m (--mirror) option. You can refine things with other
options (such as those to avoid certain files or types, useful to exclude
those extra ?D=A indexes from directory listings) but I usually start with
-r -k -np. On a Windows system? Telnet to a Unix machine. There is a
Windows port, but I'm not sure how good it is.
wget can limit the total size of a download by setting a quota, but it's
not as useful as you might think. Better for you to decide yourself where
to split a collection over two or more CDs. Of course some sites make this
easy (like PUPS/TUHS, for which I run one of the official mirrors).
Another polite option is --wait, which waits between fetches to reduce the
bandwidth. Some sites might not like you hogging their connection. In
fact, recently I came across another site that had banned certain addresses
altogether for attempting to download a whole site without asking first.
The owner took the view that no-one could possibly want the whole site,
unless for a mirror, in which case it's best to ask.
Some sites have a megabytes-per-month limit imposed by their ISP, so again,
ask.
There are also programs for FTP (only) mirroring: the imaginatively-named
'mirror' and 'ftpmirror' come to mind, and pavuk too, but wget is a pretty
good all-rounder.

I agree. Anyway, you don't need a PET for that. An SBC like a KIM-1 is
much better; you can wedge it right into the gap under the door.

On the Mac... iCab will let you pull down most of a site, it is limited
by the number of levels you tell it to follow links. It will place it all
in a folder, and keep the directory structure in tact (ie: subdirectories
go into sub folders), so that you can just start at the top, and follow
the links locally.
Other than that... I think the other app that I have heard recommended (I
use iCab myself), is called Site Sucker, or Web Sucker, one of those...
it too will pull everything down, retaining links as it goes.

Yup... I have that radius card I think. I have a video card that was in
the SE FDHD you sold me (well, really just tossed in the box along with
the Classic II). I can double check the card when I am at work tomorrow
(working from home today). Do you want the card back... or do you want to
give me the monitor when I am up there? :-D

For the most part... still boxed... been busy writing CATI jobs. I think
I am going to skip copying the manuals... too darn big, too darn hard. If
I drop the manuals, the rest will just take me a day to organize and get
ready to bring to you.
What's a good weekend for me to make the drive? (Its looking like Sundays
are my only open weekend days until the 2nd weekend in March... after
that Sat or Sun is fine)

No, he wrote "one or 2 ... *complete* reference" (my emphasis). Per
system.
> Without documentation an old computer is worthless.
Agreed. Absolutely. Whenever I find old kit, I look around and ask around
for any and all manuals, documents, whatever.
As for complete, here's what I'd consider "complete", for, say, an 11/40
(like the one I got last year):
- complete printsets for all boards etc, a pile about 6" to 12" high.
- complete set of diagnostics (XXDP) listings, 12" - 18" wide on a shelf
- manuals for the CPU, bootstrap loader, DL11-W, etc etc, 6" wide
- technical manuals ditto for the RX02, RK05s, etc, 6" - 12"
- manual set for RT-11 or RSX-11 and languages etc, 20" - 40" of shelf
space
- IC and other components references, Texas Instrument TTL handbook, etc,
etc
- probably other things I've forgotten.
That 11/40 came with some of the original logbooks but not the invoices
etc. My 11/34 even had some of the original orders and invoices,
installation sheets, and the like.
As for the suggestion someone made that you can get documentation from the
web, well, that's sometimes true, but often the information is incomplete,
or in an unsuitable format, or disappears after a while. I can't count
the number of times I've been grateful that I downloaded a copy of some
document onto one of my own hard drives, because the original online
version has gone. Besides, a printed copy is often much more useful,
especially for circuit diagrams and large manuals.

I don't know. Something heavier is probably better. Maybe a PET?
A small mini/deskside would certainly hold a door open well...
or anything in a BA23 enclosure with floor-stand.
A commodore 128 also might have a chance of actually wedging into
the space between the door and the floor.

Hello,
I am also interested in the classic computers and am currently researching
