beware identical Toshiba
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. 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.--Numeric (talk))

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.

The floppy drive is also used in the following Thinkpad units, the 360, 355, 370, 701, 755, & 760.
