==beware other implementations of 17 mm connector==

Toshiba used a same connector as IBM (17 mm 26 pin).  Like ThinkPad parts, they are abundant in secondhand market.  I wonder if they are compatible; I did not test, myself. [http://www.vintage-computer.com/vcforum/showthread.php?22879-Any-info-on-this-laptop I found only one user report (IBM floppy with Toshiba PC), and that user reports failure, not compatible.]  How unfortunate, IBM and Toshiba did not choose identical wiring plan.--[[User:Numeric|Numeric]] ([[User talk:Numeric|talk]]))
+
Also Toshiba and Apple used the same ''connector'' (17 mm 26 pin) as IBM.  Their implementations are contrary, noncompatible.
 +
 
 +
Toshiba used a same connector and ''different wire/pin assignment''.  Like ThinkPad parts, they are abundant in secondhand market.  How unfortunate, IBM and Toshiba did not choose identical wiring plan.

IBM, Dell, and Toshiba used 21mm D connector in several external diskette drives.  These attach to host using a modular/detachable cable.  ''Mercifully, these three makers chose compatible wiring.''  (Also Apple used this connector, in FDD for Macintosh PowerBook 2400.  Apple FDD hardware is incompatible to IBM PC FDD hardware.)

17 mm

Floppy cable connector — ThinkPad side (770) — width: 17mm

By year 2000, IBM made this their standard host-side connector for external floppy diskette drive. This D-shell connector has 26 pins. It is found in ThinkPad and Dock product lines, and SurePOS 500.

Models featuring 17 mm connector

NOTE!
These devices only feature pass-through functionality, the actual Floppy Controller logic needs to reside in the ThinkPad for the port to work

beware other implementations of 17 mm connector

Also Toshiba and Apple used the same connector (17 mm 26 pin) as IBM. Their implementations are contrary, noncompatible.

Toshiba used a same connector and different wire/pin assignment. Like ThinkPad parts, they are abundant in secondhand market. How unfortunate, IBM and Toshiba did not choose identical wiring plan.

The plug is a perfect fit, but unfortunately, the laptop will not power on with the floppy plugged in. Additionally, the laptop will not power on with the cable plugged in while the floppy drive is not connected to the cable.

Despite the cable for a Toshiba and one of the IBM ones having the same connector, they are NOT interchangable. I blew a fuse in a Toshiba that way.

Tip by Kasm279 on forum.thinkpads.com.

Apple used a same connector in Macintosh PowerBook 2400. Apple Macintosh floppy interface is incompatible to IBM PC floppy interface. Despite being made by IBM, PowerBook 2400 uses different wiring. Tip by MikeatOSX and sambapati87.

17 mm drive Options

The most compact Option is Part (FRU) 84G8663, designed for and PC110. This has a non-removable cable which plugs-in to 17mm host.

20 mm

Floppy cable connector — ThinkPad side (365XD) — width: 20mm

This D shell connector has 26 pins (seems to be the same like 17 mm, but a little bigger).

NOTE!
IBM used this same connector in ThinkPad 760 MIDI/Game Port. Be careful not to confuse different peripheral cables. Tip by Ziginox.
ATTENTION!
Also Toshiba produced a cable with same connectors as IBM 74H0219. Toshiba 20mm connector pinout is different: at the very least, pins for power and ground are shorted relative to IBM. Tip by Ziginox.

701

Bob Collins wrote on forum.thinkpads.com:
The cable for the flop looks like a mini SCSI (external) connector with 36 gold contacts. The width of the connector is approx 1".

NDCaesar wrote on forum.thinkpads.com:
The 701 uses an unusual connector for the external floppy drive. It looks like a wider version of the connector on the 10H4056 floppy drive itself. The trapezoidal part is ~26mm wide and the same height as the one on the drive, with identical clips on either side.

21 mm drive

Floppy cable connector — drive side — width: 21mm

IBM, Dell, and Toshiba used 21mm D connector in several external diskette drives. These attach to host using a modular/detachable cable. Mercifully, these three makers chose compatible wiring. (Also Apple used this connector, in FDD for Macintosh PowerBook 2400. Apple FDD hardware is incompatible to IBM PC FDD hardware.)

parallel port

ThinkPad T20 line supports a floppy drive connected to Parallel Port. Other portable PCs featured this functionality (notably Compaq Armada M700, Dell Latitude LS, and Toshiba), but each company chose different wiring, so a non-IBM parallel floppy drive is NOT substitutable. The adapter (FRU P/N: 08K6360; other number (ASM?) 08K6359) provides a 17 mm D receptacle.
