This page is about floppy diskettes. There is a lot of information about floppy drives and S-100 on this page, including Web links. (There was also 'classic' hard drive information here: that info is now on another Web page.)To contact me, or for ordering information follow this link.To return to my S-100 list click here.

Conditions and categories of diskettes
For all disks, pease specify SINGLE or DOUBLE SIDED (important) and SINGLE or DOUBLE DENSITY (less critical, I'll explain). If in doubt, describe or send an image of the label side of one of your diskettes. Used diskette sets will be matched by brand as stocks allow. Brands include IBM, 3M, Verbatum, Dysan and others. We have some 'no brand' unlabled disks also.
Write protected diskettes:8-inch diskettes may have a 'write protect notch' on thefront edge of the envelope. Here's a photo of that notch. If that notchis exposed as shown in the photo - your diskette cannot be written or formatted. You must put a smalllable or dark tape over it. Small reflective labels are shown in the photo. Meanwhile, 5.25' diskettes have a notch on the SIDE, and it must be OPEN to permit write, and you must COVER it to 'write protect' the diskette. A customer returned some 8-inch disks because he did not know about 'write protect'.
Used stock comes in various descriptions and is as described, it's not junk: 'used a few times' means these were backup disks only used once or twice.
If you order a few 8-inch diskettes as above, you can add ONE punched or unpunched punch card for one dollar within the USA. By itself, 1st class USA mail - $3. If you want more, explain.
I'll provide a piece of PUNCHED PAPER TAPE for $1 if disks or punched cards are ordered. Otherwise, $3, first class USA mail.
I need your FULL SHIPPING ADDRESS for your order, payment by check or money order or 'cash' - US paper currency. Follow this ordering link for more ordering info and my email address. Orders outside the USA will cost more, I'll provide a quoted cost.
8-inch diskettes
If you want ONE or TWO 8-inch diskettes, follow this link.
multiple 8-inch diskettes for display only.
I'll consider quoting multiple diskettes for display only not use. These will be diskettes with some damage to the media but otherwise they visually appear in fair to good condition. If you have specific requests about type, condition, look, etc. etc - it will raise the price. BE SPECIFIC. Otherwise you can buy multiple disks as described below. Shipping weight per box, 1.5 lb + 1.0 lbs per ten
8-inch diskettes, unused old stock , brand name, in boxes of ten: sealed boxes are opened and inspected, see the notes above.

CP/M and S-100 floppy disk controllers
If you 'want CP/M to run on my S-100 system', pleaseread my Frequent Questions page and my 'how to run CP/M' Pagefor answers to thatquestion. If you want docs for YOUR S-100 controller, check my lists of card manufacturers tosee if I have the manual for your card. I have a few floppy controllercards for sale but in general I'd rather you ask for a SPECIFIC manufacturerand brand of card rather than 'just any'. However I do have one brandand model available for general interests. Check mySD Systems Versafloppy II page for the status of S-100 Versafloppy IIcontroller cards and software in my stock.
I have docs, with source code, for many S-100 floppy disk controllers. If you are debugging or repairing a floppy disk controller that is NOT S-100, you may find one ofthese manuals useful. they are listed by manufacturer and model; start from myS-100 home page to search the lists of manuals. Also, check my list of S-100 Web pointersfor sites which also have docs for controllers, or FDC chips such as the Western DigitalWD1771, 1773, 1793, and so on. The same considerations apply to older hard disk controllers of course.
Buying floppy drives
Ordering floppy drives
Floppy drive power requirements
Various 8-inch floppyd drive cabinets are available, ask for details. Shippingextra, weight and size is considerable, espeically with power supplies. These are almost always non-switching supplies. Size about 19 inches wide, several inches high,various depths. With the power supply in the back, these can be 24 inches deep. Mostare intended for 'full height' drives.
For purchase, please note your location by city/state/zipwhen inquiring for shipping estimates. Not shipped outside the USA - are you kidding? If you are interested in empty cabinets, PLEASE note what kind of power connector your drives have: there are several varieties. Supply limited, cables also limited.Prices subject to change.
Here's a stack of some 8-inch cabinets
a single 8-inch cabinet
another 8-inch cabinet
A rather sleek drive cabinet was theHeath/Zenith Z-207-41 tabletop 8' drive cabinet. Autocad notes 2015 in hindi pdf. A tan cabinet on rubber feet, with power supply and fan, power switch on front. I have a few of these left, I use them regularly, so I'm not likely to sell one - it's a good example. Shipping weight is 40 lbs for cabinet and power supply, with two drives it typically weighs 55 lbs. A 30-page manual is available, ask for a price for a copy.
floppy and hard Drive Documentation
All documentation photocopied at a per-page fee plus postage and handling. I will quotea price when you order, check my ordering information .Ask for manuals for your specific drive, by manufacturer and model number. Ifyou have a manual I don't, I'd be interested in a trade or purchase ofcopies. If you need a manual for a drive not listed below, contact me soI can get look for it!
Often I get requests for 'just the jumper information'. It turns out the jumper info typically is several pages depending on the manual, not just one. And you may or may not need more info from the manual, either to set the jumpers or to maintain or repair the drive, or in some cases the pinouts of the drive connector. But, assuming the jumper info is six pages or less, I'll charge $2 to pull the manual and copy those pages, plus postage and handling to send those pages in a business letter type envelope at several ounces weight by air mail. (Remind me of this policy if you choose it.)

Some people ask: 'I want to read 8-inch diskettes on my PC/Windows/Linux machine. Please sell me a complete system, or tell me where to get one.' Often they have no idea how this might be accomplished. Other people want to read CP/M oer other non-MS-DOS 5.25' or 3.5' diskettes, or old Mac 400K or 800K 3.5' Mac diskettes, on a Windows PC. Folks, this is not a 'plug and play' project. A few people want to read really ODD formats - hard sectored, M2FM, and so on. Until Sept 2011 I had information on this subject, on this Web page. How to read and write 'old' floppy diskettes now has it's own Web page, look there for details. Links below to the old discussion, now link to the new Web page. - Herb Johnson
floppy drive controllers with conversion, imaging software - Discussion of various PC based floppy controllers is moved, look there for details.
A reference to Sydex, ANADISK and 22DISK is also moved to the Web page on How to read and write 'old' floppy diskettes
Catweasel floppy controller - The Catweasle discussion is moved look there for details.
Software to support foreign diskettes on Windows-based PC's - is moved to another WEb page, look there for details.
Check my 'how to CP/M' Web page for more discussion of Dave Dunfield's imagedisk software tools, and his collection of system disk images.
