I am seeing similar issues shopping for 1GB 200-pin CL 2.5 PC2700 DDR for the not-that-old Thinkpad T42. Mobo slots limited to (2) 1GB SODIMMs, no advantage to faster than PC2700/DDR333 but could apparently use PC3200 if I could find it in 200-pin SODIMM (?). -- Bill n1vux at arrl.net bill.n1vux at gmail.com
