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) 19:31, 30 July 2015 (CEST)

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