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