Either these sites have both got some kind of database error and the type 1872 belongs to another Thinkpad family, or there is some kind of T23 forgotten bastard child that IBM have disowned... I suspect the former, although nothing would surprise me!
On further inspection the T43 has a type 1872 so mystery solved. I guess beware of those memory companies and always check with the IBM site to see what your older thinkpad is capable of!
