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.

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.
