No one's mentioned the problem that you'll also need to convert
the *data* once you've moved the *files*. Which word processor
created the files, and which contemporary word processor do you
hope to use them in? You may need to revive the original machine
or something similar in order to re-save the documents in ASCII.
Conversion programs might be available, but that might cost $$$.
Of course, you'll need to run 22Disk on a PC equipped with both
5 1/4 and 3 1/2 floppies, then move the files to a 3 1/2 PC disk, and
the Mac can read them as-is.

Yo! Right here in my desk drawer. Used this one through High School
(graduated 1980). The teachers cut me some slack on the 3rd digit from time
to time.

Right - and it's fast, and the readout is visible in any lighting condition
in the cockpit (if you can't read an E6B, navigation is *not* your main
problem!) and you can drop it about as far as you want and it'll be OK. I
have never used an electronic E6B, for all those reasons.

Wow...I didn't think this thread would lead to massive array parallel
processing *or* supercomputing...but you never know! ;-)

Nickolas & everyone else on this thread:
Again, I _really_ disagree with this tip. It shouldn't make any difference as
to the name. I renamed the files to .dsk and it really didn't make any
difference at all, for me anyway. Just wanted to reiterate that myself and
many, many other users have not had this problem either.

Fair summary, except that I'd have said 'the format lives on in 5.25"
HD' - IBM introduced the HD 5.25 inch diskettes to behave as much as
possible like 8 inch ones, even though that meant different magnetic
properties of the oxide from conventional 5.25". And IBM had enough
clout that this displaced the existing 80 track formats right out of the
market. IBM PCs that have HD drives have an 8 inch disk controller
controlling them.
So in summary, an 8 inch disk holds as much as a 5.25 inch one, although
older formats held less...
Now, does anyone know how much a 14 inch floppy held? (it was 14, wasn't
it?) For that matter, who else has ever seen one?
We had a drive at IBM which was bigger than the PC it plugged into. The
disk (I only ever saw the one!) was in a white card envelope instead of
the conventional black plastic one, and the slot where the head went in
was along one of the diagonals, but otherwise I remember blank-all about
it.

Well, a fellow winner of the "Geek Site Of The Day" Award. I mention
your site on my site, the Terak Museum, which won on October 16, 1996.

I mean, a paper is flat, and a board is (mostly) flat too, so why wouldn't
I be able to scan it? Answer is, I can. It works fine. The only bug
is the board is bigger than the scanner... I'll be retryin throughout the day,
you can see the pictures at http://209.174.127.164/pdp8
Tell me what you think! Oh, and I wouldn't try this with anything with
EPROMs on it... :)

Microsoft Announces XENIX OS
Microsoft announces Microsoft XENIX OS, a portable operating
system for 16-bit microprocessors. It is an interactive, multi-user,
multi-tasking system that will run on Intel 8086, Zilog Z8000, Motorola
M68000, and DEC PDP-11 series. All of Microsoft's existing system
software (COBOL, PASCAL, BASIC and DBMS) will be adapted to
run under the XENIX system, and all existing software written for
UNIX OS will be compatible as well.
