I found a ten-pack of 8-inch floppy disks that have me confused. They're
from STAM@, a name I've never heard of before.
It's clear that they're
hard-sectored, but the index and sector holes are
along the outer edge.
There's also a notch cut into the corner. Both of these appear to be done
in an attempt to restrict users to a single vendor of floppies.
Here are some pics:

Those look suspiciously like floppies for the Memorex 650/651 -- the
first commercially available read/write floppy drive (1972). I just
picked up a 651 myself (mostly because it looks cool, I can only hope to
someday have a machine to use it with...) If you're willing to spare
one of those disks (so I have a matching set) let me know... :).

Those type of 8 inch disks are used in the Incoterm series intelligent
terminals. Here is a little bit of information about my Incoterm terminal:

The disks I have are made by Verbatim.

They might actually be the Memorex 650 media. The 650 media had 8 sector (9
holes) while the 651 media had 32 sectors (33 holes)
See
http://www.textfiles.com/bitsavers/pdf/memorex/disc/2944.010_650floppyOEM.pd
f, Fig 3
Or
http://www.textfiles.com/bitsavers/pdf/memorex/disc/2644.002-01_651Maint_Nov
74.pdf , Fig. 1-5
Or they might be for one of the other early FDD vendors such as Century Data
or Potter, but they really look like the Memorex FDs
With the shipment of IBMs 33FD the indes/sector hole moved to the center as
did the rest of the industry, starting with the Shugart 900 series.
Memorex had enough volume in the early FDDs that third parties such as
Verbatim made compatible media.

David,
I think these might actually be Stamco brand. One of my uncles had a
machine that used a disk that looked like this but unfortunately he
can't remember any of the details. This was back in the mid- to
late-70's, I think and he only had it for a short time as I recall. If
one of us remembers anything more I'll post additional info.
Regards, Brian.
