 One interesting thing about this specific model is its support for Pentium III processors up to 1Ghz, but only for Coppermine cores and at the expense of massive heat & battery power draw increase.There is a 1200-XL302 (with model number "12XL302") too.It is equipped similar to the XL502A - with the difference of an Celeron processor with 600 MHz and an AsKey modem in the MiniPCi slot.
