17 mm

Floppy cable connector — ThinkPad side (770) — width: 17mm
sketch of 17 mm-wide external floppy connector

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 line, and SurePOS.

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 identical Toshiba

Toshiba used a same connector as IBM (17 mm 26 pin). 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.

drive Options

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

ThinkPad T Series FDD External Cable Kit

This cable connects Ultrabay 2000 Floppy Drive to host with 17 mm D connector. End of cable with Ultrabay 2000 connector has thumbscrews, for a rigid connection, semi-permanent attachment. IBM Option P/N 27L0524; FRU P/N 27L0525; other P/N (ASM?) 27L0526. Support Document MIGR-4JTSXJ Support Document MIGR-40010

UltraslimBay Floppy enclosure

This enclosure houses UltraslimBay Floppy Drive, connects to host with 17 mm D connector.

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".

Tip by Bob Collins on forum.thinkpads.com.

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.

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.
