There is a lot of information about floppy drives and S-100 on this page, including Web links. Until June 2009, 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.

here is how to order or to contact me
Please review the information below before you buy or use diskettes. The more you know the better decisions you will make. We also have a technical page on floppy diskettes and drives.
For all disks, pease specify SINGLE or DOUBLE SIDED (important) and SINGLE or DOUBLE DENSITY (less critical). If in doubt, read or send an image of the label side of one of your diskettes. Used diskette sets will be matched by manufacturer as stocks allow. Manufacturers include IBM, 3M, Verbatum, and others.
Used stock comes in various descriptions and is as described, it's not junk: "used a few times" means these were backup disks and well kept. Brands include IBM, Verbatium, Inmac, Dysan, 3M - if you have brand preferences we'll try to accomodate.
Diskettes are specified by "density" of recording. "single density" and "double density" use the SAME diskette media (coating) and only require reformatting by you, on your computer. "high density" is a different media (coating); we don't recommend using high-density diskettes as single or double density; you cannot reliably use double-density diskettes for high-density use.
Notes on 8-inch diskettes sold:. Due to age, we are obliged to open sealed boxes, inspect, and possibly test EACH 8-inch diskette sold, unless sold AS IS. Even on the shelf and sealed, these decades-old diskettes can become damaged, their surfaces become brittle and dry. If you insist on an originally-sealed box, you assume ALL RISKS OF USE.
We will bulk erase disks to reduce "soft" errors;
"Bulk erase" means to use an AC electromagnet or bulk tape eraser to stir up
the magnetic domains after years of sitting still: believe it or
not they tend to hold their positions after many many years.
Please review the information above before you buy or use diskettes. The more you know the better decisions you will make.
Note: review the information above about 8-inch single density and double density before ordering.
We often get requests for ONE 8-inch floppy diskette, usually to settle a bet or for show or for a gag gift. Every order takes time and effort to process, even this kind of order. We'll send ONE clean 8-inch diskette in a paper envelope by first class mail within the USA for $5 total. I need your FULL SHIPPING ADDRESS for your
order, payment by check or money order or a $5 bill. 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.
unused old stock, brand name, sealed in boxes of ten:
NOTE: for used disks below, we'll try to provide them all of one brand
per set of ten. Give us a few choices of brand if you have a preference.
8" DSDD, lightly used once to a few times, with sleeves: $19 per ten + ship.
8" SSSD, lightly used once to a few times. Single Sided, single density,
name brands with original sleeves. $19 per ten plus ship. .
8" SSDD, lightly used once to a few times.Single Sided, double density
price $XX per ten + ship. ***OUT, use SSSD instead*** See
this Web page for more information.
lables for 8" disks, $1 per ten
5.25" soft sectored: not for sale by me, these are common enough. 3.5" 800K (720K) 3.5" double sided DOUBLE density (not high density). Unused old
stock, sealed. Great for older Mac/Apple equipment, some old computers and
PC's. Can also use as 400K (360k) (single sided) diskettes. While available,
$19 a box of ten in SEALED boxes, with lables. (boxes will be unsealed before sale
and disks tested due to age.
1.4M 3.5" diskettes - widely available elsewhere.
Tough plastic cases for 8-inch diskettes, slightly larger than a box of
ten 8-inch diskettes. Will hold several diskettes loosely,
maybe 15 tightly packed with their envelopes. Various styles and colors,
can be stacked or shelved vertically like books. Some styles will fold
open and sit on your desk at a convenient angle for easy access. Many
available at $15 each plus shipping. A typical way diskettes fail in
long storage is due to mold: these boxes provide some moisture protection
as well as some physical protection.
If you "want CP/M to run on my S-100 system", please
read my Frequent Questions page for that
question. If you want docs for YOUR S-100 controller,
check my lists of card manufacturers to
see if I have the manual for your card. I have a few floppy controller
cards for sale but in general I'd rather you ask for a SPECIFIC manufacturer
and brand of card rather than "just any". However I do have one brand
and model available for general interests. Check my
SD Systems page for the status of Versafloppy II
controller 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 of
these manuals useful. they are listed by manufacturer and model; start from my
S-100 home page to search the lists of manuals. Also,
check my list of S-100 Web pointers
for sites which also have docs for controllers, or FDC chips such as the Western Digital
WD1771, 1773, 1793, and so on. The same considerations apply to older hard disk controllers of course.
At this time (2003), I have SOME 8-inch floppy drives for sale,
tested and working; I prefer to sell replacments by manufacturer and model
number . Drive cabinets are priced as below
and may be available, ask for availability. At the moment I'm busy with
support efforts, including a manuals service and my Mac business, so
availability of tested drives and cabinets is limited. This may change
if customer interest dictates, so I appreciate encouragments.
You are welcome to request specific drives, by name and model number; or
request specific needs for 8-inch drives or related items. Any working drive
sold is tested for read, write, seek but not tested or adjusted for alignment.
We cannot guarantee that all diskettes can be read by drives we sell, due to
possible misalignment, wear or damage to those diskettes; and of course any
limitations of your software or hardware when used with these drives.
Supplies are obviously limited. We may offer a trade-in value on selected
8-inch drives in reasonable condition: ask and describe your drives. Shipping
costs are based on packed weight, varying from 10 to 30 lbs for one drive, the
latter for full-height 8-inch drives. Documentation for drives is at extra cost,
see below. Cabinets and power supplies for drives are described below. Drives which are 5.25 inch, 3.5 inch, or 3 inch use +5 volts and (for the
5.25 inch drives) +12 volts. 8-inch drives use +5V, +24V, and in many cases
110VAC 60Hz for the spindle motors.
You should confirm your power supply connectors will mate with
whatever drive you get. There are a few configurations of power
connectors: all 8" drives use a 50-pin edge connector for data and control.
Some drive motors run off 110AC, many 8-inch drives (including the
half-heights) use 24V DC for the stepper and spindle and +5 volts to power their logic. Some early drives
(Shugart 800) require -5 volts, or a source of negative several volts,
to power the read/write circuits. (Shugarts have a jumper to include
or short out a -5 volt regulator.). 5.25 inch drive and 3.5 inch drives
use +12 volts and +5 volts, some 3.5 inch drives only need +5 volts. Also, watch for drive model numbers and model variations. For instance,
the Shugart 800 vs the 801 is only a matter of some jumper changes. But,
there are later models of the 800/801 with entirely different circuitry.
If you want from me a "matching" drive down to the chips and jumpers, or
a manual for exactly that model, make a photocopy or photo of the drive's
circuit board and send it with your order and keep it for reference. Various available, ask for details. Shipping
extra, weight is considerable. Please note your location by city/state/zip
when inquiring for shipping estimates. 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.
A rather sleek drive cabinet was the
Heath/Zenith Z-207-41 tabletop 8" drive cabinet. A tan cabinet on rubber feet,
with power supply and fan, power switch on front. An image of this drive
is available via this link .
Supports one or two half height 8-inch drives, would also
support one full height drive. Drives sit horizontally. Cable is 50-pin flat
cable with shielding and black plastic cover.
There was a manual for the cabinet and for the drives Heath/Zenith offered
with them. I only have a few of these left, I use them regularly. Shipping
weight was 40 lbs for cabinet, with two drive 55 lbs. A 30-page manual
is available, ask for a price for my copy service.
Other rack or tabletop 8-inch drive cabinets, various manufacturers. Holds
two full-height drives, side by side. Size about 19 inches wide, 5 inches high,
various depths. Includes power supply. Some available with full-height
drives. A few cabinets available with vertical half-height drives, ask!
I have some various 8-inch drive cabinets of other sorts, with power supplies.
Prices depend on what drives you plan to use - please specify those drives!
Shipping extra, weight varies. Prices subject to change based on
effort and availability. I have several cabinets in stock, as time permits
I will list them by size and features.
Note: a cabinet's power supply for YOUR drives will require a mating power
connector and will have specific voltage requirements: an adaptor may be necessary,
see the discussion on this page.
The drive manuals listed below have a variety of information. Typically the older drive
manuals (8-inch and 5.25 inch drives) have detail specifications, a list of jumper (option) settings,
a description of circuit operation, a list of signals on the drive connector, and often schematics.
Later manuals have less information. A clue is the number of pages listed (we charge by the page,
and of course any info in the title. You can ask us if you are in doubt, but we generally don't provide
an entire index or table of contents upon request.
All documentation photocopied at a per-page fee plus postage and handling. I will quote
a price when you order, check my ordering information .
Ask for manuals for your specific drive, by manufacturer and model number. If
you have a manual I don't, I'd be interested in a trade or purchase of
copies. If you need a manual for a drive not listed below, contact me so
I 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.)

Many people ask me "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, as though you could just plug-in a USB 8-inch floppy drive! ;) Other people want to read (or write) CP/M diskettes, or very old Mac 400K 3.5" Mac diskettes, on a Windows PC.
To my knowledge, no one sells a "complete" system of hardware and softwre to do the above. To read 8-inch floppy drives on a "PC", you can in principle connect 8-inch drives to a PC'/s floppy controller; you "just" need a drive, with power supply; a 50-pin cable; a connector to adapt the 50-pin cable to your 34-pin floppy controller; and software or software knowledge! Even with that, MOST PC floppy controllers won't read single-density format anyway!
Reading non-MS-DOS disks on a PC, even with the right sized floppy drive, can be difficult. The floppy CONTROLLER on the PC, which does all the work of reading, writing, and formatting, may not be able to accept non-MS-DOS formats, even WITH software. The early Apple disk formats use odd bit patterns for instance. Or it can simply be a problem with knowing which of the MANY MANY CP/M disk formats you need to use with your particular diskettes.
In Feb 2005 there were some discussions in popular newsgroups, about converting old CP/M systems from 8-inch and 5.25-inch floppy drives, to 3.5" drives and media. Issues raised included support of FM or single density; finding old media; choices of formats. I decided these discusssions were worth preserving, as these issues come up over and over. One
discussion was in the Classic-comp CCTECH discussion.
The other occurred in Usenet discussion group comp.os.cpm.
a good Web site for using 8-inch CP/M diskettes on PC's is my colleague David Dunfield's Web site. Check my discussion of Dunfield's disk site elsewhere on this page.
It can be a challenge to use 5.25-inch "quad density" drives on modern computers, or modern floppy drives on older computers.
The Web page linked here describes how to adapt a Teac FD-55GFR 1.2M drive to use for 800K (96TPI) formatted diskettes. Other notes there may apply to other brands of 1.2M drives. Note that the Web page is copywrited by the author, the Web link is to a licensed copy of that work.
5.25-inch to 8-inch cabling adapters
As for 34-pin to 50-pin adapters, you could build one. The CP/M FAQ has a diagram; I've not checked it so no guarantees. Here's a copy of the description from the CP/M FAQ. Dave Dunfield's specific notes for attaching 8-inch drives to PC's are at at this Web page under "Notes on connecting 8 inch and external floppy drives".. You may find problems adapting this to specific drives, as some signals may be used differently. This is not a "plug and play" solution! No guarantees! That's why my Web site has all this information and references, OK?
If you want to buy an adapter, consider D Bit's 8-inch floppy disk adapter for 8-inch drives on
PC\windows systems. While they don't provide PC software for CP/M diskettes, they do have an MS-DOS utility for PDP-11 diskettes called "PUTR" that may be relevant. While this adapter was still listed at dbit.com as of 2007, their supply and services may vary.
Some years ago, there were a series of floppy controllers for PC/Windows systems branded as the Compaticard product line. Some of them used internal floppy drives, some supported external floppy drives. Some of them could read Apple II and Mac diskettes. In any event, these products are long out of production. So I don't "cover" the Compaticard here on this Web page. Other Web sites cover that product line, a Web search may find them.
Also some years ago, there were the Central Point Option Board products. These were ISA bus boards (for old IBM-PC compatibles well before the Pentium) which provided ways to copy either Apple or Mac diskettes, or old "copy protected" diskettes. I found a reference in a comp.sys.tandy Usenet group discussion in 2010 to this Web page about the Central Point products, including manuals photos and software. Again, search the Web for information on this old product line.
Since 2000 or so, there's been a series of products built for use with PC's called Catweasel. Follow this link for more
Catweasel information.
SOme CP/M systems (and systems like the Apple II) used disk formats that conventional floppy disk controller boards can't read. There is/was a program and a bit of hardware called "Disk2FDI" which is described at this Web page. It uses a PC and a cable between a 5.25-inch floppy drive and the parallel port, and is said to be able to read Apple II and Commodore diskettes. A trial version is free to read only; there is a registration fee to get the registered version, from Europe.
Since about 2008, there's been a number of hobby-class projects to use programmable logic devices or embedded microprocessors as programmable floppy controllers. Search the Web for these as they come and go. In 2010, one project is Kryoflux, an ARM processor programmed to read floppy data streams.
I can sell you drives and cases and cables. But you'll still need that 50-to-34 adapter. As for a controller, in my opinion, your best bet is to buy a seperate floppy controller. As of 2006, I don't offer a PC compatible controller, or that adapter. But, one company which DOES offer a very adaptable floppy controller for the PCI bus is Jens Schönfeld of Individual Computers, who produces the "Catweasel IV" controller. The controller does NOT include a 50-pin connector for 8-inch drives.
The Catweasel IV floppy controller product is produced in Germany by Jens Schönfeld of Individual Computers. It is sold by some US companies. This product is primarily intended to support Amiga systems by providing a floppy controller and Amiga-type hardware to support Amiga emulation on Windows-type PC's. I regret to say, that it's hard to find current information about the Catweasel on the Individual Computer Web site, And, software development for it is scattered among a number of sites and people and operating systems. I frankly suggest a Google search, to see who is doing what "currently". I'll try to provide some directions on this Web page.
Many people are using these controllers for 8-inch floppy drives, or to read and write 5.25-inch and 3.5-inch Mac and Apple disks, or TRS-80 disks. And if you can program, this may be an option for running 8-inch drives with wierd formats on a Windows PC. The older Catweasel products were ISA 8-bit cards; some may still be available on the used market. Since late 2004, the Mark IV model is on a PCI card. (In 2010, they have a new PCI model.
This site seems to be a catweasel distributor.)
for some more Catweasel discussion, check my Web page on using it for old Intel diskettes.
The Individual Computers site lists distributors for the CatWeasel Mark IV, or you can buy direct from Germany, or in 2010 there were some new cards offered on eBay. One support source for TRS-80 and other uses is Tim Mann's TRS-80 pages on the Catweasel. A Web search will find discussion group posts about specific uses of this product, or sites with more info and software for use.Go to my S-100 pointers page for possible links to other Catweasel sites or software developers. There's apparently several people who have developed software for use with this card. In 2009 I was alerted to Karsten Scheibler's site; there is software there plus links to other developers. There's also a
Catweasel discussion group on Yahoo but it's not terribly active. Again, a Google search may be more productive.
A number of software tools were developed under MS-DOS, to read earlier (and later) non-MS-DOS disk formats. I'll collect information on these products here. - Herb Johnson
One software product to read old CP/M diskettes was provided by Sydex Inc. and called "Anadisk" and "22disk". This product was offered in trial form at no charge, as well as a licensed form for a fee. Several years after its introduction, the rights to the products were sold and it's no longer available. But the originator of these products offers some degree of support to ORIGINAL licensees. Check this Web page for further history and discussion, including my correspondence with Chuck Guzis, president of Sydex and author of these programs.
Check my "how to CP/M" Web page for more discussion of Dave Dunfield's imagedisk tools and system disk images. Dave's program transfers disk contents to an "image" file which can be used with his program to recreate the original diskette. He also has
software tools on his site to test PC's floppy controllers and drives.
Omniflop is a freeware product to read
foreign diskettes on Windows-based PC's. Check the Web link for details. They have an older product, Omnidisk which runs under MS-DOS. These products read whole contents of a diskette, they apparently don't interpret the image into a file system (CP/M, FAT13, etc.). The site refers to other programs which do.
