PC-66

This is 66MHz SDRAM memory in 144-pin SO-DIMM form-factor.

SO-DIMM

Available memory types from IBM

Partnumber FRU Description
76H0293 42H2818 16MB PC66 SDRAM 3.3v NP SO-DIMM

01K1153		 128MB PC66 SDRAM 3.3v NP SO-DIMM
NOTE!
As PC-66 memory is getting increasingly difficult to aquire, PC-100 or PC-133 memory can be used instead. Using PC-100 or PC-133 memory will not increase system performance, as it will be run at only PC-66 speed.
