I know this is a strange request for help, but I have done a lot of
searching for sources of odd sized floppy disks, and haven't had much luck.
The 8" disks are not so much a problem, but from what I can tell, there were
2.0, 2.5, 2.8, 3.0, 3.25, and 4.0 inch formats and finding even one example
has become a challenge for me. Since 3" disks were popular with the
Sinclair systems, these can be had off Ebay, but what of the rest? Its a
personal quest to one one copy of every type of removable media and if
anyone has any ideas, sources, information, it would be most appreciated. I
hope to post the collection to a website as I don't think it has been done.
Thanks for any input
Kurt
(Still seeking a copy of the manual for the Jupiter Ace 4000, but I am
hopeful as there is one possible source if I am lucky)

I have a Panasonic Video Floppy player that uses a 2" or 2.5" disk to hold
still images. I never have done anything with it, since I didn't know
where to get the disks. The remote for the unit is also missing, which I
was told limits the functionality of it quite a bit.

There's a guy at the MIT swap meet and the TCF
that sold them for $6/ea from 1999-2002, and,
hopefully now. I have one here if you need more
details.
If you really want one and can't go I could get it for
you.

Zenith used 2" disk in one of their laptops, I think it was called a Mini-Sport.
I've found the machines and disk on both E-bay and at hamfest. I used to have two
drives and about 13 or 14 disks but gave them away. Mike Haas got them.
I gave Don Maslin the 3" drive and disk that I used to have. You can try to talk
him out of them.
There was a 3 1/4" disk advertised on E-bay just recently. I may have the
seller's address if you can't find it by searching E-bay.

and I sent him a 3.25" diskette. But I doubt that he would part with any
unless he had duplicates.

Yeah, I've got that box in front of me right now. Fuji Film Floppy Disk
LT-1, 2 inch, 10-pack (DSDD, 245TPI, 80 tracks) specifically for the Zenith
Minisport and compatibles. Each teenee floppy has it's own jewele-t case...
classy. I wonder if they'll fit in my Canon Xapshot. I can send out a few
disks, send email.

To be correct Amstrad liked 3" discs not Sinclair, when Amstrad brought
Sinclair they added them to the Spectrum. Sinclair liked Microdrives.
Nintendo 64 DD drives use weird disks. 4x4x0.4 inch discs holding 64Mb with
variable writable range (from 1-38Mb), it was only released in Japan.

The original 3.5" had no shutter. The ones that I have are labeled
"Shugart".
The next ones had a completely manual shutter. YOU opened it, YOU closed
it.
Then came the "one way", or "pinch" shutter. You opened it manually,
and
to close it, you squeezed the corner of the disk. A few drives would open
the disk for you, but you still needed to pinch the corner to release the
shutter to close it. Some current disks still have the arrow that points
to where you pinch it.
Then came the current style that opens AND closes it for you.
The 3.25" is a much more interesting story (Dysan bet the company on it)
At one time, the journalists were arguing about 3 v 3.25 v 3.5, as "shirt
pocket disks". MOST of them got it wrong. George Morrow had the
solution, "Let's just payoff the clothing business to make 5.25" shirt
poskets."

> 2.9"
There were a couple of 2.5"
and a couple of 2.9" One was a spiral track,
and one (TEC?) was the same as a 720K 3.5" (80 track, etc.)
3.9"
Who used them; who made them? Do you have a handy chart, Fred? 3.5"
(early ones without shutter, manual shutter, one-way shutter,
floptical)
"One-way shutter"?

Interesting. Have you got a sample?

I think I have one.

Ah. The first 3.5" disk I ever owned was an HP labeled disk with a pinch
shutter (I still have it somewhere).
Then came the current style that opens AND closes it
for you.
Technology marches on.

No, but I'd like a copy.
