Hi (CMOS battery)

Picture: (From an 1998 Siemens laptop Simatic PG720P.)

+ What type of connector does it have ?
+ What kind of battery to select for max.capacity ? (Original 1998 is: 3.6V cr1/2 AA)
+ Where can I find cheap 72-pin 32mb so-dimm memory for it ? (No notch !)
-> Ebay's memory is expensive 20-40$/per piece and I would like 4pcs for full 128mb ram.

Why does these 1990s laptops sell for 800-1500$ in ebay ? (I could buy a new modern Siemens PG for 2000$)
